delete one document from index not working

[Behnam Khoshsafar <b....@hamgam.ir>]

I'm using Lucene 5.1.0 to index a document and search it. I have a lot of documents, over 1000000, which are stored in a database. When I start running the project for the first time, I use Lucene to index these documents. Now I want to delete one document from the database and indexes. I also choose an id for each index. I am using the following command to delete, but it's delete all index.

iw.deleteDocuments(new Term("id", doc.id));
Also, I used a Query to delete but it's delete all index.

I add documents to the index as follows:

iDoc = new org.apache.lucene.document.Document();
FieldType fieldType = new FieldType();                        
fieldType.setIndexOptions(
IndexOptions.DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS);
fieldType.setTokenized(true);
fieldType.setStored(true);
fieldType.setOmitNorms(true);
fieldType.setStoreTermVectors(true);
fieldType.setStoreTermVectorOffsets(true);
fieldType.setStoreTermVectorPayloads(true);
fieldType.setStoreTermVectorPositions(true);
iDoc.add(new Field("id", doc.id.toString(), fieldType));
iw.addDocument(iDoc);

You should not setTokenized(true) for your id field?  This splits it
into tokens according to your analyzer.
