Exact matching is just one of my cases. Currently I perform search on field
with given definition:
<fieldType name="text_general" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1" preserveOriginal="1" types="characters.txt"/>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory"
language="English"/>
</analyzer>
<analyzer type="query">
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1"
catenateWords="1" catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1" preserveOriginal="1" types="characters.txt"/>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory"
language="English"/>
</analyzer>
</fieldType>
This field definition fullfils all other requirments.
Examples:
- special characters
- passengers<-> passenger
The case with exact matching is the last one I have to complete.
The problem with cats <-> cat is caused by SnowballPorterFilterFactory. This
is what I know.
The question is whether it is possible to handle exact matching (edismax)
with only one result like described in the previous post without influencing
existing functionalities?
