Define an Analyzer that does not lowercase the id field, e.g., something
like:
public class MyAnalyzer extends Analyzer {
private Analyzer standard = new StandardAnalyzer();
public TokenStream tokenStream(String field, final Reader reader) {
if ("id".equals(field)) {
return new WhitespaceTokenizer(reader);
} else {
return standard.tokenStream(field, reader);
}
}
}
Then pass this into QueryParser.
