--------------------------------------
Hi Simon,
You shouldn't need to build a custom Solr to get this to work for you. Just
put the jar file provided in your lib directory and adjust your solrconfig.xml
file acordingly. I just tried it out with the solr-4.5.1.zip binary and worked
just fine to get term positions for the includes field in the example.
You did bring to my attention that the getUniqueKeys isn't necessary. It looks
like a copy/paste error from the PostingsSolrHighlighter. New patch to follow.
I'm just running all the steps suggested in the HowToContribute wiki.
Thanks,
Tricia

> Project: Solr
> Issue Type: New Feature

> Attachments: SOLR-4722.patch, solr-positionshighlighter.jar

> 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.
