Hi All,
I have a use case where I need to Search like this-
"Apple Corporation Limited" should create the pairs like -Apple
Corporation,Corporation Apple,Corporation Limited,Limited Corporation.
Below is the filter I am using-
<fieldType name="text_shingle" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.PositionFilterFactory" />
<filter class="solr.ShingleFilterFactory" minShingleSize="2"
maxShingleSize="2" outputUnigrams="false" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ShingleFilterFactory" outputUnigrams="false"
minShingleSize="2" maxShingleSize="2" outputUnigramIfNoNgram="true" />
</analyzer>
</fieldType>
Below are the issues I am facing-
1)This only allows me to search like a phase query.I mean to say I does
allows "Apple Corporation" but does not allow Apple Corporation.
2)Also I need to know how I can search for -Corporation Apple .
3)I want to restrict single word search like Apple.I mean to say apple
should not give me any results.
Please suggest.
Regards,
Vibhor Jaiswal
