Lucene.Net query with leading wildcard

Good afternoon,

I need to be able to search a Lucene.Net index with a wild card prefix; i.e. now when I search for the word "paint" "autopaint" does not come up, but I need it to.

I have seen mentioned "SetAllowLeadingWildcard" elsewhere in Stack Overflow, but I don't see that property - maybe because I'm using Lucene.NET?

Thanks, Mo

Which version of Lucene.Net are you using? The SetAllowLeadingWildcard property is on QueryParser in v2.1.

To be able to search for paint and get autopaint back as a result, you would have to search for *paint. Searching for paint would not return autopaint.

Take heed of the note in the comments on the property though:

Note that this can produce very slow queries on big indexes.
