I think one of the advantages may be the analyzers and processors that are already available for several documents types.
Using regex with these is nearly impossible. -----Original Message----- From: Doug Cutting [mailto:[EMAIL PROTECTED] Sent: Friday, April 15, 2005 6:16 PM To: java-dev@lucene.apache.org Subject: Re: [Performance] Streaming main memory indexing of single strings Wolfgang Hoschek wrote: > The classic fuzzy fulltext search and similarity matching that Lucene is > good for :-) So you need a score that can be compared to other matches? This will be based on nothing but term frequency, which a regex can compute. With a single document there'll be no IDFs, so you could simply sum sqrt() of term regex match counts, and divide by the sqrt of the length of the string. Yes, I'm playing devil's advocate...
