[jira] [Commented] (SOLR-3390) Highlighting issue with multi-word
synonyms causes to highlight the wrong terms
[ https://issues.apache.org/jira/browse/SOLR-3390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13289270#comment-13289270 ]
Okke Klein commented on SOLR-3390:
----------------------------------
Using multi word synonyms works a lot better in LUCENE_33 because of the way SlowSynonymFilter handles them. Is there a way to get the same behavior with the new filter?

> Key: SOLR-3390
> URL: https://issues.apache.org/jira/browse/SOLR-3390
> Project: Solr
> Issue Type: Bug
> Components: highlighter, query parsers
> Affects Versions: 3.6
> Environment: Windows 7. (Development machine, not the server)
> Reporter: Rahul Babulal
> Labels: highlighter, multi-word, solr, synonyms
>
> I am using solr 3.6 and when I have multi-words synonyms the highlighting results have the wrong word highlighted.
> If I have the below entry in the synonyms file:
> dns, domain name system
> If I index something like: "A sample dns entry explaining the details".
> Searching for "name" (without quotes) in the highlight results/snippets I get : "A sample dns <em>entry</em> explaining the details". (The token "entry" overlaps with the token "name" in the analysis.jsp)
> Searching for "system" (without quotes) in the highlight results/snippets I get : "A sample dns entry <em>explaining</em> the details". (The token "explaining" overlaps with the token "system" in the analysis.jsp)
> Here is my schema field Type:
> <fieldType name="text_general" class="solr.TextField" positionIncrementGap="100">
