upper case in wildcard query (SolrQueryParser issue)

[Yongtao Liu]

Hi all,

If user do wildcard query and the term has upper case (like Hell*), the query 
will not return result.

I saw in org.apache.lucene.queryParser.QueryParser has function 
setLowercaseExpandedTerms to handle this.
Via comments, looks like default value should be true.
But in SolrQueryParser, it hardcode this value to false.
I was wondering why SolrQueryParser set it to false by default?

org.apache.lucene.queryParser.QueryParser
  /**
   * Whether terms of wildcard, prefix, fuzzy and range queries are to be 
automatically
   * lower-cased or not.  Default is <code>true</code>.
   */
  public void setLowercaseExpandedTerms(boolean lowercaseExpandedTerms) {
    this.lowercaseExpandedTerms = lowercaseExpandedTerms;
  }

org.apache.solr.search.SolrQueryParser
  public SolrQueryParser(IndexSchema schema, String defaultField) {
    super(schema.getSolrConfig().getLuceneVersion("luceneMatchVersion", 
Version.LUCENE_24), defaultField == null ? schema.getDefaultSearchFieldName() : 
defaultField, schema.getQueryAnalyzer());
    this.schema = schema;
    this.parser  = null;
    this.defaultField = defaultField;
    setLowercaseExpandedTerms(false);
    setEnablePositionIncrements(true);
    checkAllowLeadingWildcards();
  }


Thanks,
Yongtao
