-----------------------------------
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>
