Re: Search for null

If you want performance, a better way might be to assign some special string/value (if it's easy to create) to the missing field of docs and index the field without tokenizing it. Then you may search for that special value to find the docs. Jay Les Fletcher wrote: Does this particular range

Re: Lucene 2.2 + Not Merging Segments

This is spooky. Could you provide more details about how you are using IndexWriter? Are you changing "max buffered docs" from the default? Also, can you call writer.setInfoStream(System.out), capture that log, and post it? Mike "Harini Raghavan" <[EMAIL PROTECTED]> wrote: > Hi All, > > I jus

Synonym Search and stemming

Hi, I want to implement synonym search in my application. I think there are two ways to implement synonym search. Index the documents using a synonym analyzer OR Expand the query using a parser which uses a synonym analyzer. Well I am expanding query as indexing with synonym analyzer takes muc
