As far as I know there is no built-in analyzer that uses whitespace tokenizer
and lowercase filter together. But it is easy to cast tokenizer and token
filters to create a new analyzer. You said that you were using
SnowballAnalyzer, right? Just replace tokenizer from standard to whitespace.
Edit SnowballAnalyzer.java :
public TokenStream tokenStream(String fieldName, Reader reader) {
TokenStream result = new WhitespaceTokenizer(reader);
result = new LowerCaseFilter(result);
if (stopSet != null)
result = new StopFilter(result, stopSet);
result = new SnowballFilter(result, name);
return result;
}
By changing this method you can create custom analyzers. If you do not want
stemming just erase the line that contains SnowballFilter, etc. Since you have
lowercasefilter in your analyzer, your wildcard queries should be lowercased.
Alternatively you can set setLowercaseExpandedTerms(true) of your QueryParser.
