Is there a way to generate separate index files from a single one based on some sort of rule without reindexing the documents again? The original index contains none-stored fields which means I can't read documents and add them to the destination index. One option mentioned in SO is to clone the index into many and then delete the docu...

The problem is that the standard analyzers/tokenizers treat the whole camel case source code identifier name as a single token. I'm looking for a way to treat camel case identifiers like MaxWidth into three tok...
Some of the documents I store in Lucene have fields that contain file paths or URIs. I'd like users to be able to retrieve these documents if their query terms contain a path or URI segment. For example, if the path is C:\home\user\research\whitepapers\analysis\detail.txt I'd like the user to be able to find it by queriying for path...
I've got a Sitecore application, which creates and uses a number of Lucene indexes through Sitecore's built-in API. I need to make sure that items in the index are kept up-to-date when they are published. To do this, I've created a Sitecore Hook that detects when and item is saved to the "web" database and reindexes the item. It seems ...

This is what I'm planning to do and I'd appreciate anyone's input: I've built a forum in Asp.net MVC and now want to add Lucene.Net for search. My plan is to run an index builder thread every 5-10 minutes to update the search index with the changes made to the each discussion. The way it will work is I keep the date and time for the l...
