Hi, I've a .net windows service which generates Lucene search indexes every night.

The code below is from the Lucene In Action book (originally in Java). It's for building a list of 'allowed' documents (from a user permission point of view) to filter search results with. The problem is the termsDocs.Read() method does not accept the 'doc' and 'freq' arrays to be passed by reference, so they're still empty when it comes...

Update I've been looking around the NHibernate.Search.Tests project to find out how the Criteria API is used (i find it immensely useful to look around the test code to have working examples) and i noticed that the way to use the Fulltext search is radically different. Here are two tests, one with the criteria API, one with the classic ...

My problem is how do I pass this w...

Hi all, I'm using Lucene .NET I've got 2 threads, each one doing indexing of some different content (using a different algorithm, although they might try to index the same document). They are both writing to the same index (using a single IndexWriter instance). Also, I've got a web application that also needs to write to the index occ...
Hello all, I have an indexing function named "Execute()" using IndexWriter to index my site's content. It works great if I simply called it from a web page, but failed when I have it as a delegate parameter into System.Threading.Thread. Strangely though, it always work on my local dev machine, it only fails when I uploads to a shared ho...
