I'm getting very odd behavior from a wildcard search.
For example, when I'm searching for docs with a name containing the word
"International" the following occur:
q=name:(inte*) -- found "International"
q=name:(intern*) -- found "International"
q=name:(interna*) -- did not find "International"
q=name:(internat*) -- did not find "International"
.. adding 1 character at a time did not find "International"
q=name:(international*) -- did not find "International"
As indicated, the behavior is quite bizarre and causing issues with our use
and test cases. Is there something I can set for the fieldType of text in
order to make these kinds of searches working? Also, any insight as to why
this is not working would be a big help as well.
Pasted for reference:
<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<!-- in this example, we will only use synonyms at query time
<filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
-->
<!-- Case insensitive stop word removal.
add enablePositionIncrements=true in both the index and query
analyzers to leave a 'gap' for more accurate phrase queries.
-->
<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"

</analyzer>
</fieldType>
