- *
- * <h3>Introduction</h3>
- *
- * <div>
- *
- * <p>This document defines the index file formats used in this version of Lucene. If you are using
- * a different version of Lucene, please consult the copy of <code>docs/</code> that was distributed
- * with the version you are using.
- *
- * <p>This document attempts to provide a high-level definition of the Apache Lucene file formats.
- * </div> <a id="Definitions"></a>
- *
- * <h3>Definitions</h3>
- *
- * <div>
- *
- * <p>The fundamental concepts in Lucene are index, document, field and term.
- *
- * <p>An index contains a sequence of documents.
- *
- * <ul>
- * <li>A document is a sequence of fields.
- * <li>A field is a named sequence of terms.
- * <li>A term is a sequence of bytes.
- * </ul>
- *
- * <p>The same sequence of bytes in two different fields is considered a different term. Thus terms
- * are represented as a pair: the string naming the field, and the bytes within the field. <a
- * id="Inverted_Indexing"></a>
- *
- * <h4>Inverted Indexing</h4>
- *
- * <p>Lucene's index stores terms and statistics about those terms in order to make term-based
- * search more efficient. Lucene's terms index falls into the family of indexes known as an
- * <i>inverted index.</i> This is because it can list, for a term, the documents that contain it.
- * This is the inverse of the natural relationship, in which documents list terms. <a
- * id="Types_of_Fields"></a>
- *
- * <h4>Types of Fields</h4>
- *
- * <p>In Lucene, fields may be <i>stored</i>, in which case their text is stored in the index
- * literally, in a non-inverted manner. Fields that are inverted are called <i>indexed</i>. A field
- * may be both stored and indexed.
- *
- * <p>The text of a field may be <i>tokenized</i> into terms to be indexed, or the text of a field
- * may be used literally as a term to be indexed. Most fields are tokenized, but sometimes it is
- * useful for certain identifier fields to be indexed literally.
- *
- * <p>See the {@link org.apache.lucene.document.Field Field} java docs for more information on
- * Fields. <a id="Segments"></a>
- *
- * <h4>Segments</h4>
- *
- * <p>Lucene indexes may be composed of multiple sub-indexes, or <i>segments</i>. Each segment is a
- * fully independent index, which could be searched separately. Indexes evolve by:
- *
- * <ol>
- * <li>Creating new segments for newly added documents.
- * <li>Merging existing segments.
- * </ol>
- *
- * <p>Searches may involve multiple segments and/or multiple indexes, each index potentially
- * composed of a set of segments. <a id="Document_Numbers"></a>
- *
- * <h4>Document Numbers</h4>
- *
- * <p>Internally, Lucene refers to documents by an integer <i>document number</i>. The first
- * document added to an index is numbered zero, and each subsequent document added gets a number one
- * greater than the previous.
- *
- * <p>Note that a document's number may change, so caution should be taken when storing these
- * numbers outside of Lucene. In particular, numbers may change in the following situations:
- *
- * <ul>
- * <li>
- * <p>The numbers stored in each segment are unique only within the segment, and must be
- * converted before they can be used in a larger context. The standard technique is to
- * allocate each segment a range of values, based on the range of numbers used in that
- * segment. To convert a document number from a segment to an external value, the segment's
- * <i>base</i> document number is added. To convert an external value back to a
- * segment-specific value, the segment is identified by the range that the external value is
- * in, and the segment's base value is subtracted. For example two five document segments
- * might be combined, so that the first segment has a base value of zero, and the second of
- * five. Document three from the second segment would have an external value of eight.
- * <li>
- * <p>When documents are deleted, gaps are created in the numbering. These are eventually
- * removed as the index evolves through merging. Deleted documents are dropped when segments
- * are merged. A freshly-merged segment thus has no gaps in its numbering.
- * </ul>
- *
- * </div> <a id="Overview"></a>
- *
- * <h3>Index Structure Overview</h3>
- *
- * <div>
- *
- * <p>Each segment index maintains the following:
- *
- * <ul>
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90SegmentInfoFormat Segment info}. This
- * contains metadata about a segment, such as the number of documents, what files it uses, and
- * information about how the segment is sorted
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90FieldInfosFormat Field names}. This
- * contains metadata about the set of named fields used in the index.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90StoredFieldsFormat Stored Field values}.
- * This contains, for each document, a list of attribute-value pairs, where the attributes are
- * field names. These are used to store auxiliary information about the document, such as its
- * title, url, or an identifier to access a database. The set of stored fields are what is
- * returned for each hit when searching. This is keyed by document number.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90PostingsFormat Term dictionary}. A
- * dictionary containing all of the terms used in all of the indexed fields of all of the
- * documents. The dictionary also contains the number of documents which contain the term, and
- * pointers to the term's frequency and proximity data.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90PostingsFormat Term Frequency data}. For
- * each term in the dictionary, the numbers of all the documents that contain that term, and
- * the frequency of the term in that document, unless frequencies are omitted ({@link
- * org.apache.lucene.index.IndexOptions#DOCS IndexOptions.DOCS})
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90PostingsFormat Term Proximity data}. For
- * each term in the dictionary, the positions that the term occurs in each document. Note that
- * this will not exist if all fields in all documents omit position data.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90NormsFormat Normalization factors}. For
- * each field in each document, a value is stored that is multiplied into the score for hits
- * on that field.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90TermVectorsFormat Term Vectors}. For each
- * field in each document, the term vector (sometimes called document vector) may be stored. A
- * term vector consists of term text and term frequency. To add Term Vectors to your index see
- * the {@link org.apache.lucene.document.Field Field} constructors
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90DocValuesFormat Per-document values}. Like
- * stored values, these are also keyed by document number, but are generally intended to be
- * loaded into main memory for fast access. Whereas stored values are generally intended for
- * summary results from searches, per-document values are useful for things like scoring
- * factors.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90LiveDocsFormat Live documents}. An
- * optional file indicating which documents are live.
- * <li>{@link org.apache.lucene.codecs.lucene90.Lucene90PointsFormat Point values}. Optional pair
- * of files, recording dimensionally indexed fields, to enable fast numeric range filtering
- * and large numeric values like BigInteger and BigDecimal (1D) and geographic shape
- * intersection (2D, 3D).
- * <li>{@link org.apache.lucene.backward_codecs.lucene92.Lucene92HnswVectorsFormat Vector values}.
- * The vector format stores numeric vectors in a format optimized for random access and
- * computation, supporting high-dimensional nearest-neighbor search.
- * </ul>
- *
- * <p>Details on each of these are provided in their linked pages. </div> <a id="File_Naming"></a>
- *
- * <h3>File Naming</h3>
- *
- * <div>
- *
- * <p>All files belonging to a segment have the same name with varying extensions. The extensions
- * correspond to the different file formats described below. When using the Compound File format
- * (default for small segments) these files (except for the Segment info file, the Lock file, and
- * Deleted documents file) are collapsed into a single .cfs file (see below for details)
- *
- * <p>Typically, all segments in an index are stored in a single directory, although this is not
- * required.
- *
- * <p>File names are never re-used. That is, when any file is saved to the Directory it is given a
- * never before used filename. This is achieved using a simple generations approach. For example,
- * the first segments file is segments_1, then segments_2, etc. The generation is a sequential long
- * integer represented in alpha-numeric (base 36) form. </div> <a id="file-names"></a>
- *
- * <h3>Summary of File Extensions</h3>
- *
- * <div>
- *
- * <p>The following table summarizes the names and extensions of the files in Lucene:
- *
- * <table class="padding4" style="border-spacing: 1px; border-collapse: separate">

- *
- * <h3>Lock File</h3>
- *
- * The write lock, which is stored in the index directory by default, is named "write.lock". If the
- * lock directory is different from the index directory then the write lock will be named
- * "XXXX-write.lock" where XXXX is a unique prefix derived from the full path to the index
- * directory. When this file is present, a writer is currently modifying the index (adding or
- * removing documents). This lock file ensures that only one writer is modifying the index at a
- * time. <a id="History"></a>
- *
- * <h3>History</h3>
- *
- * <p>Compatibility notes are provided in this document, describing how file formats have changed
- * from prior versions:
- *
- * <ul>
- * <li>In version 2.1, the file format was changed to allow lock-less commits (ie, no more commit
- * lock). The change is fully backwards compatible: you can open a pre-2.1 index for searching
- * or adding/deleting of docs. When the new segments file is saved (committed), it will be
- * written in the new file format (meaning no specific "upgrade" process is needed). But note
- * that once a commit has occurred, pre-2.1 Lucene will not be able to read the index.
- * <li>In version 2.3, the file format was changed to allow segments to share a single set of doc
- * store (vectors & stored fields) files. This allows for faster indexing in certain
- * cases. The change is fully backwards compatible (in the same way as the lock-less commits
- * change in 2.1).
- * <li>In version 2.4, Strings are now written as true UTF-8 byte sequence, not Java's modified
- * UTF-8. See <a href="http://issues.apache.org/jira/browse/LUCENE-510">LUCENE-510</a> for
- * details.
- * <li>In version 2.9, an optional opaque Map<String,String> CommitUserData may be passed to
- * IndexWriter's commit methods (and later retrieved), which is recorded in the segments_N
- * file. See <a href="http://issues.apache.org/jira/browse/LUCENE-1382">LUCENE-1382</a> for
- * details. Also, diagnostics were added to each segment written recording details about why
- * it was written (due to flush, merge; which OS/JRE was used; etc.). See issue <a
- * href="http://issues.apache.org/jira/browse/LUCENE-1654">LUCENE-1654</a> for details.
- * <li>In version 3.0, compressed fields are no longer written to the index (they can still be
- * read, but on merge the new segment will write them, uncompressed). See issue <a
- * href="http://issues.apache.org/jira/browse/LUCENE-1960">LUCENE-1960</a> for details.
- * <li>In version 3.1, segments records the code version that created them. See <a
- * href="http://issues.apache.org/jira/browse/LUCENE-2720">LUCENE-2720</a> for details.
- * Additionally segments track explicitly whether or not they have term vectors. See <a
- * href="http://issues.apache.org/jira/browse/LUCENE-2811">LUCENE-2811</a> for details.
- * <li>In version 3.2, numeric fields are written as natively to stored fields file, previously
- * they were stored in text format only.
- * <li>In version 3.4, fields can omit position data while still indexing term frequencies.
- * <li>In version 4.0, the format of the inverted index became extensible via the {@link
- * org.apache.lucene.codecs.Codec Codec} api. Fast per-document storage ({@code DocValues})
- * was introduced. Normalization factors need no longer be a single byte, they can be any
- * {@link org.apache.lucene.index.NumericDocValues NumericDocValues}. Terms need not be
- * unicode strings, they can be any byte sequence. Term offsets can optionally be indexed into
- * the postings lists. Payloads can be stored in the term vectors.
- * <li>In version 4.1, the format of the postings list changed to use either of FOR compression or
- * variable-byte encoding, depending upon the frequency of the term. Terms appearing only once
- * were changed to inline directly into the term dictionary. Stored fields are compressed by
- * default.
- * <li>In version 4.2, term vectors are compressed by default. DocValues has a new multi-valued
- * type (SortedSet), that can be used for faceting/grouping/joining on multi-valued fields.
- * <li>In version 4.5, DocValues were extended to explicitly represent missing values.
- * <li>In version 4.6, FieldInfos were extended to support per-field DocValues generation, to
- * allow updating NumericDocValues fields.
- * <li>In version 4.8, checksum footers were added to the end of each index file for improved data
- * integrity. Specifically, the last 8 bytes of every index file contain the zlib-crc32
- * checksum of the file.
- * <li>In version 4.9, DocValues has a new multi-valued numeric type (SortedNumeric) that is
- * suitable for faceting/sorting/analytics.
- * <li>In version 5.4, DocValues have been improved to store more information on disk: addresses
- * for binary fields and ord indexes for multi-valued fields.
- * <li>In version 6.0, Points were added, for multi-dimensional range/distance search.
- * <li>In version 6.2, new Segment info format that reads/writes the index sort, to support index
- * sorting.
- * <li>In version 7.0, DocValues have been improved to better support sparse doc values thanks to
- * an iterator API.
- * <li>In version 8.0, postings have been enhanced to record, for each block of doc ids, the (term
- * freq, normalization factor) pairs that may trigger the maximum score of the block. This
- * information is recorded alongside skip data in order to be able to skip blocks of doc ids
- * if they may not produce high enough scores. Additionally doc values and norms has been
- * extended with jump-tables to make access O(1) instead of O(n), where n is the number of
- * elements to skip when advancing in the data.
- * <li>In version 8.4, postings, positions, offsets and payload lengths have move to a more
- * performant encoding that is vectorized.
- * <li>In version 8.6, index sort serialization is delegated to the sorts themselves, to allow

- * <li>In version 9.1, vector-valued fields were modified to add a graph hierarchy.

- * <h3>Limitations</h3>
- *
- * <div>
- *
- * <p>Lucene uses a Java <code>int</code> to refer to document numbers, and the index file format
- * uses an <code>Int32</code> on-disk to store document numbers. This is a limitation of both the
- * index file format and the current implementation. Eventually these should be replaced with either
- * <code>UInt64</code> values, or better yet, {@link org.apache.lucene.store.DataOutput#writeVInt
- * VInt} values which have no limit. </div>

- * <li><b>[int8]</b> if equals to -1, dense – all documents have values for a field. If equals to
- * 0, sparse – some documents missing values.
- * <li>DocIds were encoded by {@link IndexedDISI#writeBitSet(DocIdSetIterator, IndexOutput, byte)}
- * <li>OrdToDoc was encoded by {@link org.apache.lucene.util.packed.DirectMonotonicWriter}, note
