Solr autocomplete feature

[Ilayaraja . P]

Hi

 I want to change autocomplete implementation for our search. Current I have a 
suggest field whose definition in schema.xml is as below:

       <field name="suggest" type="edgytext" indexed="true" stored="true" 
required="true" omitNorms="false"/>

        <fieldType name="edgytext" class="solr.TextField" 
positionIncrementGap="0">
                <analyzer type="index">
                        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
                        <filter class="solr.WordDelimiterFilterFactory" 
generateWordParts="0" splitOnCaseChange="0" splitOnNumerics="0" 
catenateWords="1" catenateNumbers="1" catenateAll="1"/>
                        <filter class="solr.LowerCaseFilterFactory"/>
                        <filter class="solr.EdgeNGramFilterFactory" 
minGramSize="2" maxGramSize="10" />
                </analyzer>
                <analyzer type="query">
                        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
                        <filter class="solr.LowerCaseFilterFactory"/>
                </analyzer>
        </fieldType>


It works as follows.
"shoes" will match "casual shoes", "sports shoes", "shoes" etc.


Whereas I want it to match only the values that starts with the user query.
Ie. If user types "shoes", I want suggest terms that starts with "shoes" (or) 
has the query string as prefix string in "suggest" filed in the index.

Please let me know how to do this.
