Forest Soup updated SOLR-4722:
------------------------------
Attachment: PositionsSolrHighlighter.java
Thanks a lot for the patch!
I did some modification based on the original patch to meet our project special
needs. This modification reveals each term's text as well as its position and
offsets.
We do not need solr to do the highlighting but just return the positions and
offsets. So in schema.xml, our field does not stored and only have
termVectors="true" termPositions="true" termOffsets="true".
Just share it.
> 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.

> URL: https://issues.apache.org/jira/browse/SOLR-4722
> Project: Solr
> Issue Type: New Feature
> Components: highlighter
> Affects Versions: 4.3, 6.0
> Reporter: Tricia Jenkins
> Priority: Minor
> Attachments: PositionsSolrHighlighter.java, SOLR-4722.patch,

> 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.
