Basically a user starts typing the first letters of a city and I want to
return citynames that start with those letters, case-insensitive and not
splitting the cityname on separate words (whether the separator is a
whitespace or a "-").
But although the search of a user is case-insensitive, I want to return the
values including casing, search on "new york" would return "New York", where
the latter is how it's stored in my MS-SQL DB.
I've been testing my code via the admin/analysis page.
I believe I don't want the WhitespaceTokenizerFactory on my field definition
since that splits the city names I want the following behavior:
query on:
"new*" returns "New york" or "newbee", but does not return values like
"greater new hampshire"
"york*" does NOT return "new york"
"nij*" returns "Nijmegen", but not "Halle-Nijman"
Here's what I have come up so far:
<field name="title" type="text_lower_exact" indexed="true"
stored="true"/>
<field name="title_search" type="text_lower_exact" indexed="true"
stored="true"/>
<fieldType name="text_lower_exact" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_dutch.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</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_dutch.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
But when I leave out the WhitespaceTokenizerFactory I get: Plugin init
failure for [schema.xml] fieldType "text_lower_exact": analyzer without
class or tokenizer,trace=org.apache.solr.common.SolrException: SolrCore
'tt-cities' is not available due to init failure
