[jira] [Comment Edited] (SOLR-4722) Highlighter which generates a
list of query term position(s) for each item in a list of documents, or
returns null if highlighting is disabled.
[ https://issues.apache.org/jira/browse/SOLR-4722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633305#comment-13633305 ]

---------------------------------------------------------------
Loosely related to SOLR-1954 and SOLR-1397. SOLR-1954 is looking at exposing offsets and score in addition to snippets. SOLR-1397 is looking to highlight external fields, say from a database, with a Solr highlighter (and analysis).

> As an alternative to returning snippets, this highlighter provides the (term) position for query matches. One usecase for this is to reconcile the term position from the Solr index with 'word' coordinates provided by an OCR process. In this way we are able to 'highlight' an image, like a page from a book or an article from a newspaper, in the locations that match the user's query.
> This is based on the FastVectorHighlighter and requires that termVectors, termOffsets and termPositions be stored.
