Solr Scoring

[Kissue Kissue]

Hi,

I have a field in my index called itemDesc which i am applying
EnglishMinimalStemFilterFactory to. So if i index a value to this field
containing "Edges", the EnglishMinimalStemFilterFactory applies stemming
and "Edges" becomes "Edge". Now when i search for "Edges", documents with
"Edge" score better than documents with the actual search word - "Edges".
Is there a way i can make documents with the actual search word in this
case "Edges" score better than document with "Edge"?

I am using Solr 3.5. My field definition is shown below:

<fieldType name="text_en" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.StandardTokenizerFactory"/>
               <filter class="solr.SynonymFilterFactory"
synonyms="index_synonyms.txt" ignoreCase="true" expand="false"/>
             <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
             <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.EnglishMinimalStemFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords_en.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPossessiveFilterFactory"/>
        <filter class="solr.KeywordMarkerFilterFactory"
protected="protwords.txt"/>
        <filter class="solr.EnglishMinimalStemFilterFactory"/>
      </analyzer>
    </fieldType>

Thanks.
