Re: is lucene fit for doing this?

I would say Lucene is a capable of helping you do this. Remember that it is a set of libraries and you have to build the functionality you need with that. BUT with a little planning and elbow grease you will be able to use it to create a great search engine. Good luck. On Jan 29, 2008,

Query in Lucene 2.3.0

Hi all. Lucene latest version - 2.3.0 says that the default behaviour of flushing from memory to file-system based index is based upon RAM usage - with 16 MB being the default value. Fine. Works for me, as long as I am using a single thread to write into the index. However, I have been trying to

Luke for Lucene 2.3?

Hi, Has anyone tried Luke v0.7.1 with the latest Lucene build, v2.3? I'm getting "Unknown format version: -4" error when opening Lucene 2.3 index with Luke 0.7.1. Is there any upgraded version of Luke anywhere? I also read something about web-based Luke, but can't find it in the contrib in 2.3,

Re: Some Help needed in search.

You can add phrase on the writer field. I.e. with high boost of 3 and low boost of 2, writing 'h' for 'heading' and 'w' for 'writer', try this query: h:sachin^3 d:tendulkar^3 w:sachin^2 w:tendulkar^2 w:"h:Sachin Tendulkar"^6 On Jan 29, 2008 9:23 AM, Sure <[EMAIL PROTECTED]> wrote: > > Hi Al

Re: Word / Pharse match shown in a context

Look at the Highlighter in contrib. It creates fragments (context) and highlights search terms in them (keywords). If you want to highlight Phrase's correctly, check out this issue which adds support for Spans and PhraseQuerys: https://issues.apache.org/jira/browse/LUCENE-794 Mark DURGA DE
