Need help to finalize my autocomplete

Hello,

I'm using the following code for my autocomplete feature :

The field type :

    <fieldType name="autoComplete" class="solr.TextField" omitNorms="true">
      <analyzer>
        <tokenizer class="solr.WhitespaceTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
        <filter class="solr.EdgeNGramFilterFactory" maxGramSize="20"
minGramSize="2" />
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
        <filter class="solr.PatternReplaceFilterFactory"
pattern="^(.{20})(.*)?" replacement="$1" replace="all" />
      </analyzer>
    </fieldType>

The field :

<dynamicField name="*_ac" type="autoComplete" indexed="true" stored="true"
/>

The query :
?q=*:*&fq=query_ac:harry*&wt=json&rows=15&start=0&fl=*&indent=on&fq=model:SearchQuery

It gives me a list of results I can parse and use with jQuery autocomplete
plugin and all that works very well.

Example of results :
> harry
> harry potter
> the last fighting harry
> harry potter 5
> comic relief harry potter

What I would like to do now is only to have results starting with the query,
so it should be :
> harry
> harry potter
> harry potter 5

Can anybody tell me if it is possible and so how to do it ?

Thank you !
Vincent

Hello,

I tried to replace the class as you suggested, but I still get the same
result (and not results where the query start only with the giving query).

<fieldType name="autoComplete" class="solr.TextField" omitNorms="true">
      <analyzer>
        <tokenizer class="solr.KeywordTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
        <filter class="solr.EdgeNGramFilterFactory" maxGramSize="20"
minGramSize="2" />
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.KeywordTokenizerFactory" />
        <filter class="solr.LowerCaseFilterFactory" />
        <filter class="solr.PatternReplaceFilterFactory"
pattern="^(.{20})(.*)?" replacement="$1" replace="all" />
      </analyzer>
    </fieldType>

Instead of <tokenizer class="solr.WhitespaceTokenizerFactory" /> use
<tokenizer class="solr.KeywordTokenizerFactory"/>
