-----------------------------------

             Summary: Highlighting issue with multi-word synonyms causes to highlight the
wrong terms
                 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


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">
      <analyzer type="index">
        <charFilter class="solr.HTMLStripCharFilterFactory"/>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true"
expand="true"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"
enablePositionIncrements="true" />
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.PorterStemFilterFactory"/>        
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true"
expand="false"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"
enablePositionIncrements="true" />
		<filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.PorterStemFilterFactory"/>
      </analyzer>
    </fieldType>
