See IndexReader.setTermInfosIndexDivisor() for a way to help reduce memory usage without needing to re-index.
If you have indexed fields with omitNorms off (the default) you will be paying a 1 byte per field per document memory cost and may need to look at re-indexing Cheers Mark ----- Original Message ---- From: Douglas Campos <doug...@theros.info> To: java-user@lucene.apache.org Sent: Friday, 24 April, 2009 17:36:37 Subject: Low-memory searcher Hi!
