White space at the end of a keyword return improper results

[Thamizhazhagan B]

Hi,

When we give white space at the end, Solr gives random results. If we remove 
the white space at the end, returns exact matching results.

For example:

No whitespace at end:
Keyword : "test result"
Result: This is Test Result

Whitespace at the end:
Keyword: "test result  "
Result:
This is test result
We have to undergo test
Result will come by tomorrow

To address this issue, we have created a copy field for the field 
"bodycontent_t" which is used to list the results. And used 'keyword tokenizer' 
analyzer to consider the space at the end.

Copy field is as follows:

<fieldType name="bodyContent_type" class="solr.TextField" 
sortMissingLast="true" omitNorms="true" positionIncrementGap="100" 
multiValued="false">
    <analyzer type="index">
      <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.StopFilterFactory" words="stopwords.txt" 
ignoreCase="true"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
      <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.StopFilterFactory" words="stopwords.txt" 
ignoreCase="true"/>
      <filter class="solr.SynonymFilterFactory" expand="true" ignoreCase="true" 
synonyms="synonyms.txt"/>
      <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
  </fieldType>

<copyField source="bodycontent_t" dest="bodyContentCopied"/>
  <field name="bodyContentCopied" type="bodyContent_type" stored="true" 
indexed="true" termVectors="true" termPositions="true" termOffsets="true"/>

But after the above changes, no results are return.  Please guide me how to 
handle white space at the end.

Please suggest a solution fi this. Thanks for your support.

Thanks,
Thamizh
