Re: Lucene Searching

Looks OK to me. You are searching on Item without adding any docs with that field, you could use writer.updateDocument() rather than delete and add, but those are just quibbles and don't explain your searching problem. Having done most of the hard work, why don't you adapt the code you posted int

Re: Lucene Searching

What exactly is "it"? Show us what you are indexing, how, and how you are building the query and we may be able to help. Whenever I see a report of incorrect results on a Mixed Case field I always suspect that the term is being lowercased on indexing and not at searching, or vice versa. -- Ian.

Re: Lucene Searching

I tried it and it worked, although it's having one peculiarity. When I search for Item_1 : it gives me 110 hits but when I use *Item_1* it gives me 0 hits. What mistake am I doing here? Also when I search for *341* it is giving me correct results i.e 0341-000-000-DR but it's not working for a

What does Luke show as being indexed for that field? Other useful tips at http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2BAC8_incorrect_hits.3F If that field is numeric you could use a NumericField - gets rid of problems with leading zeros. If by "I just want to get eve

Lucene Searching

Hi all, I am in a fix regarding lucene search. I know a little bit about lucene and have successfully created index and searched a lot of queries on that. My main worry is that whenever I search for let say "000" it doesn't give me any result while if I seach for "0341" it'll give me a hit. Ev

Re: Lucene searching across documents

Hello all, I'm trying to implement a vector space model using lucene. I need to have a file (or on memory) with TF/IDF weight of each term in each document. (in fact that is a matrix with documents presented as vectors, in which the elements of each vector is the TF weight ...) Please Please

RE: Lucene searching across documents

Hi Dan, My guess, though you didn't directly say so, is that you're representing each sentence/"line" as a separate Lucene document. To directly answer your question about whether inter-document relations (like database joins) are queryable in Lucene, I don't think so, other than performing mu

Lucene searching across documents

So I have a requirement where I have a directory filled with xml files. I wrote a parser to parse these files, and index all of the xml attributes and properties into documents. An example of one of these documents is below. I'm parsing sentences into words, and tagging the sentences based on certa

Hi Michael, I think there are a number of good resources on this: 1. http://lucene.apache.org/java/scoring.html covers the basics of searching. The bottom has some pseudo code as well. 2. Lucene In Action 3. Search this list and other places for information on the Vector Space Model.
