Hi, Unfortunately I can't change the way things are indexed, so I guess I need some short of utility class that will turn Martínez into Martínez and then just search for that term. I have also this problem using the StandardAnalyzer: If I search for "cádiz" in luke the query gets parsed as

Adjusting WRITE_LOCK_TIMEOUT in 1.9.1

I don't see how to adjust the value of IndexWriter's WRITE_LOCK_TIMEOUT in 1.9. Since the property org.apache.lucene.writeLockTimeout is no longer consulted, the value of IndexWriter.WRITE_LOCK_TIMEOUT is final, and there's no setter, what's the deal? Bill ---

Just a short one, it rocks in some cases (when actual BitSet/IntSet is compressable, long runs of set or clear bits...). Very good general BitSet representation I have tried it and found no bugs so far (+- 2 months of using it) Unfortunately, there is an issue with Licence (not ASF compatible :(
