Getting most likely documents of the query using phonetic filter in solr

Question

I am using solr for spell checking/ query correction. I have added solr.PhoneticFilterFactory and solr.NGramFilterFactory in fieldType to perform spell checking. It is working fine but here the problem is that I am getting number of documents of the query. I need only most likely words/documents or in similar words, we can say that nearer words/documents to the query.

Snippet of schema.xml :

<fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100">
       <analyzer type="index">         
        <filter class="solr.TrimFilterFactory"/>        
        <filter class="solr.NGramFilterFactory" minGramSize="2" maxGramSize="1000" />
        <filter class="solr.LowerCaseFilterFactory"/>
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>        
        <filter class="solr.PhoneticFilterFactory" encoder="DoubleMetaphone" inject="true"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
    </analyzer>
    <analyzer type="query">
        <filter class="solr.TrimFilterFactory"/>
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>        
        <filter class="solr.LowerCaseFilterFactory"/>       
        <filter class="solr.PhoneticFilterFactory" encoder="DoubleMetaphone" inject="true"/>
    </analyzer>
</fieldType>

Example : For a query "piece". I am getting around 780 NumFound(Number of documents). I need to reduce this counts but with most likely number of documents.
