Carlos González-Cadenas commented on LUCENE-3298: ------------------------------------------------- Dawid, I wanted to let you know that we've reached the 2GB barrier. We're using a heavily modified version of FSTLookup to create an autocomplete system over 2.3 billion queries (and growing, it will be more than 10-15B when we add the data for infix matches). In order to circumvent the 2.1GB limitation, we changed the code so that every bucket uses a different FST (as per Robert Muir's recommendation), but still we're having problems in the individual buckets because our dataset is huge. We'll give a try to this patch and will let you know.

I'm not going to work on it any time soon. -- This message is automatically generated by JIRA.
