Rahul Babulal commented on LUCENE-3668:
---------------------------------------
I'm using solr 3.6, and with luceneMatchVersion =3.6 in my solrconfig.xml I'm
still seeing issues with highlighting. However using luceneMatchVersion=3.3
fixes my issue.
Issue Details:
In my synonyms if I have:
nhl, national hockey league
If I index "Australian nhl team great" and
search-use-case 1: search for "hockey" (without quotes) in my highlighted
response snippets I get "Australian nhl <em>team</em> great".
search-use-case 2: search for "league" (without quotes) in my highlighted
response snippets I get "Australian nhl team <em>great</em>".
Here is my feildType and field definitions:
<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>
<field name="description" type="text_synonym" indexed="true" stored="true"
termVectors="true" termPositions="true" termOffsets="true" omitNorms="false"/>
