Wildcard queries don't work on untokenized fields (Lucene 2.2.0)

[Michael Böckling <Mi...@dmc.de>]

Hi!

I just discovered that it is not possible to search in untokenized fields
when using a wildcard query.

The query 

code:KP00* becomes code:kp00*

in its parsed form when it should really be "code:KP00*", as tested in Luke
using a whitespace analyzer. When omitting the wildcard character *, the
parsed query reads correctly as "code:KP00".

Is this a bug or a "feature"?

Thanks for any help!


Michael

On the 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;
  }
