Search returning 0 results for "U2"

[John G. Moylan]

We are moving from Lucene indexer and readers to a Hybrid solution where
we still use the Lucene Indexer but use Solr for querying the index.

I am indexing our content using Lucene 2.3 and have a field called
"contents" which is tokenized and stored. When I search the contents
field for "U2" using Luke the correct document turns up. However,
searching for U2 in solr returns nothing. 

Any ideas?

Lucene field is as follows:

doc.add(new Field("contents", body.replaceAll("  ", ""),
Field.Store.YES, Field.Index.TOKENIZED));

Lucene is using the following analyzer:

result = new ISOLatin1AccentFilter(result);
        result = new StandardFilter(result);
        result = new LowerCaseFilter(result);
        result = new StopFilter(result,StandardAnalyzer.STOP_WORDS);//,
stopTable);
        result = new PorterStemFilter(result);


In Solr I have the field mapped as a text field stored and indexed. The
text field uses

<fieldType name="text" class="solr.TextField"
positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.ISOLatin1AccentFilterFactory"/>
        <filter class="solr.StopFilterFactory"
                ignoreCase="true"
                words="stopwords.txt"
                enablePositionIncrements="true"
                />
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="1"
catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
      <analyzer type="query">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.ISOLatin1AccentFilterFactory"/>
        <filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
        <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1" generateNumberParts="1" catenateWords="0"
catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
      </analyzer>
    </fieldType>
