Wildcard searching and highlighting with Solr 1.4
- by andy
Hey guys,
I've got a pretty much vanilla install of SOLR 1.4 apart from a few small config and schema changes.
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<!-- default values for query parameters -->
<lst name="defaults">
<str name="defType">dismax</str>
<str name="echoParams">explicit</str>
<str name="qf">
text
</str>
<str name="spellcheck.dictionary">default</str>
<str name="spellcheck.onlyMorePopular">false</str>
<str name="spellcheck.extendedResults">false</str>
<str name="spellcheck.count">1</str>
</lst>
</requestHandler>
The main field type I'm using for Indexing is this:
<fieldType name="textNoHTML" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<charFilter class="solr.HTMLStripCharFilterFactory" />
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory"
ignoreCase="true"
words="stopwords.txt"
enablePositionIncrements="true"
/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<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.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/>
</analyzer>
</fieldType>
now, when I perform a search using
"q=search+term&hl=on"
I get highlighting, and nice accurate scores.
BUT, for wildcard, I'm assuming you need to use "q.alt"? Is that true? If so my query looks like this:
"q.alt=search*&hl=on"
When I use the above query, highlighting doesn't work, and all the scores are "1.0".
What am I doing wrong? is what I want possible without bypassing some of the really cool SOLR optimizations.
cheers!
