Bram Vereertbrugghen commented on SOLR-4722:
--------------------------------------------
As a response to [~TamerBoz]:
What I did was the following:
1. place the solr-positionshighlighter.jar into /opt/solr/server/solr/lib,
where Solr could find it. (Note: I'm running Solr in a docker container, so our
paths will be different).
2. Create the searchComponent using the above snippets and name it
'highlighter' (so I could be able to outrule duplicate naming issues).
{code:java}
<searchComponent class="solr.HighlightComponent" name="highlighter">
<highlighting class="org.apache.solr.highlight.PositionsSolrHighlighter"/>
</searchComponent>{code}
3. Create a new requestHandler explicitly using this way of highlighting.
{code:java}
<requestHandler name="/test-point" class="solr.SearchHandler">
<lst name="defaults">
<str name="omitHeader">true</str>
<str name="wt">json</str>
<str name="indent">true</str>
</lst>
<arr name="last-components">
<str>highlighter</str>
</arr>
</requestHandler>
{code}
4. Make the followinhg call:
{noformat}
http://localhost:8002/solr/mycore/test-point?hl.fl=tm_field_test&hl=on&indent=on&q=tm_field_test:test&wt=json{noformat}
This makes the call
> 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.

> Key: SOLR-4722
> 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,
> 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.
