Hi, I would like to combine a numeric range query with a term query in Lucene. For example, I want to search for documents that I have indexed that contain between 10 and 20 pages and have the title "Hello World". It does not seem possibly to use the QueryParser to generate this query for me; the range query that the QueryParser gener...

I need to index 5 of them for full text search and 3 need for sort. There might be 100,000 records. To keep my application simple, I'm thinking store all fields in Lucene index file to avo...

Hi there, I am trying to update the searching of terms of documents within my Lucene index. Currently the searches score on the number of times the term appears in the document.

If CompassGps mirroring is used with Hibernate, what happens if the database transaction rolls back? Will the changes to the index be rolled back (assuming file store for the index)? It seems like if the Lucene index is stored on the disk it won't be automatically rolled back, unless Compass is smart enough to handle that for you. FWI...

Searches need to search both a large free-text field, and a number of integer/decimal fields between different ranges, along with various functions/computations & sorting. Currently, we're handling this with a big MSSQL database, usin...

I'm in the process of updating a tool that uses a Lucene index. As part of this update we are moving from Lucene 2.0.0 to 3.0.2. For the most part this has been entirely straightforward. However, in one instance I cant seem to find a straightforward conversion. Basically I have a simple query and I need to iterate over all hits. In Luce...
I am trying to combine lucene score with PageRank, I tried to modify the DefaulySimilarity to add the PageRank I already have(in a Array with corresponding URL), but the problem is that I do not know how to get the document field which stored the URL of the document. The termDoc can only return the docID. Or I have another idea is to mod...
