Your BooleanQuery code looks fine. Do the label and abstract searches work independently? Are there docs that match both searches? There are tips on non-working searches in the FAQ at http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2F_incorrect_hits.3F
If that doesn't help I suggest you post the smallest possible self-contained example that shows the problem. -- Ian.
