Uppercase and lowercase queries
I want to query on cityname. This works when I query for example:
"Boston"
But when I query "boston" it didnt show any results. In the database is
stored: "Boston".
So I thought: I should change the filter on this field to make everything
lowercase.
The field definition for city is: <field name="city" type="string"
indexed="true" stored="true"/>
So I changed its fieldtype "string" from: <fieldType name="string"
class="solr.StrField" sortMissingLast="true" omitNorms="true">
TO:
<fieldType name="string" class="solr.StrField" sortMissingLast="true"
omitNorms="true">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
But it still doesnt show any results when I query "boston"...why?

Because you need to reindex.

Yes, and reindex. And i suggest not to use `string` as the name of the
fieldType as it will confuse later.
<field name="city" type="text_lowercase"
indexed="true" stored="true"/>
<fieldType name="text_lowercase" class="solr.TextField"
sortMissingLast="true"
omitNorms="true">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
