Solr不区分大小写的索引和搜索？

Question

Currently I am using solr5.4.1 .while Indexing is working fine, searching the data based on case -insensitive is not working.

Say I have created Projects with codes ["AnandProjectp1","AnandProjectp2","AnandProjectp3"] and names ["Project1","Project2","Project3"]

but when I am searching for code starting with q=project_code:a* or project_name:p* i am getting 0 results.

My Schema.xml is`

<field name="company_id" type="tint" stored="true" positionIncrementGap="100"/>
<field name="company_public_id" type="string" stored="true" positionIncrementGap="100"/>
<field name="company_name" type="text_en_splitting" indexed="true" stored="true" positionIncrementGap="100"/>

the schema was taken from the example schema.xml given in the examples

ou can try by following fieldType

<fieldType name="wildCardType" class="solr.TextField" sortMissingLast="true" omitNorms="true" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="50"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>

and also chnage the

<field name="project_code" type="wildCardType" indexed="true" stored="true" positionIncrementGap="100"/>
<field name="project_name" type="wildCardType" indexed="true" stored="true" positionIncrementGap="100"/>
