The thing is - StandardAnalyzer breaks on hyphen. You'll need to work around this by either extend StandardAnalyzer
>From StandardTokenizer's documentation (which is used by StandardAnalyzer): * <li> *Splits words at hyphens, unless there's a number in the token, in which case * the whole token is interpreted as a product number and is not split.* I've investigated StandardAnalyzer's tokenization and it doesn't look simple to disable that behavior. What you can do is extend StandardAnalyzer and override its tokenStream method to create a TokenStream of your own. If you know your text is space separated, you can use StringTokenizer to split the text on spaces. If a token contains '-', don't break it, otherwise pass it forward the the TokenStream returned by StandardAnalyzer. Maybe someone else has a better answer, but if you insist on using StandardAnalyzer, I have a feeling it will be problematic.
