Index evolution

Hi all. I'm very new to lucene. All I have done is read some docs about how it works, which brings to the question: How easy is to add new fields to the documents in the index? Suppose that today I can search for book title and decide that including the author in the search would be a good idea.

Multiple lock files

Hi all. How do I remove lucene locks (startup) if there are multiple applications using lucene on the same box and all use the same lock dir? -- Leandro Rodrigo Saad Cruz CTO - InterBusiness Technologies db.apache.org/ojb guara-framework.sf.net xingu.sf.net

Re: Multiple lock files
