RE: Is Lucene for Me?

It is something you have to do yourself and it depends on the requirements. One of our db-searcheengines scans the database for updates periodically (all records have a 'last-modified' field). Another of our solutions doesn`t scan the db, but is activated by a server application to update the

Terms given a filter?

Greetings - I know I can get all the fields in an index: reader.getFieldNames() and also all the terms: reader.terms() However, I need to be able to get all the terms and fields given a search filter. For example, say I have an index that has crawled 5000 pdf files (books) and I have the

Re: Terms given a filter?

This sounds like another group by totalling question. See the generic group by totalling code I posted here: http://marc.theaimsgroup.com/?l=lucene-devm=111044178212335w=2 In your example there is no quality threshold (just a filter bitset of books in 2002) so you can replace the scores array in

Thank you all for the responses. I'll try to work around this. On 9/15/05, Chris Hostetter [EMAIL PROTECTED] wrote: : : I wasn't expect addDocument to close it. : : I am wondering if there is a reason that rdr should be : : closed after addDocument, and if there is a way to leave it

Small problem in searching

Hi guys, I have some problem while searching using Lucene. Say I have some thing like tirupathireddy or venkatreddy in the index. When i search for string reddy I have to get those things (i.e. tirupathireddy and venkatreddy). I have read in Query syntax of Lucene that * will not be

Question: force a field must be matched?

Suppose I have a book index with field=publisher, field=title, etc. I want to search for books only from Manning, do I have to do anything special? how? Thanks, -James __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection

Question: dynamic sorting

Suppose I have a book index with field=publisher, field=title, etc. If a user has bought Manning books, then I like to sort the result with Manning books listed first. In essence, I'm asking for a parameterized custom sorting. Is there a way to do this? Thanks, -James

Re: Small problem in searching

Hi, I think Lucene transforms the prefix match query into all sub queries where the searching for a prefix could result into search for all terms that begin with that prefix. For postfix match, I think you need to do more work than relying on Lucene's query parser. You can iterate over the

Thanks Jason. I wonder if that's the same as queryString + publisher:Manning and pass on to the query parser? -James --- Jason Haruska [EMAIL PROTECTED] wrote: On 9/15/05, James Huang [EMAIL PROTECTED] wrote: Suppose I have a book index with field=publisher, field=title, etc. I

Hi James, Check out the org.apache.lucene.search.package, there are several sort classes that will let you write a custom sorter. If you have a copy of LIA, look at chapter 6 for an example ( http://www.lucenebook.com/search?query=custom+sort+section%3A6* ) Otis --- James Huang [EMAIL

Re: Question: dynamic sorting

Hi Otis, Thanks for your answer. I do have LIA (but not with me now physically), and have the impression that the search ordering is predetermined (at index time); what I want is search-time ordering, e.g., I'm at (x,y) now and low on gas; find me the closest airports that can land 747, the

Yes, + is what I missed! Thanks. Suppose there is a book published by 3 publishers (I don't know how that works in real world): // At index time: doc.add( Field.Keyword(publisher, Manning) ); doc.add( Field.Keyword(publisher, SAMS) ); doc.add( Field.Keyword(publisher, O'Reilly) ); // At

term scoring (idf) question

I'm trying to figure out why idf is multiplied twice into the score of a term query. It sort of makes sense if you have just one term... the original weight is idf*boost, and the normalization factor is 1/(idf*boost), so you multiply in the idf again if you want the final score to contain an
