Yeah that's a problem I noticed as well. The thing is that right now I send the query as is to the Stack Overflow servers. If I replace the spaces with OR or %20, in most cases I don't get anything back. I was looking through the API docs again but couldn't find something that'll enable substring matches either. If I don't find anything, then I can look into doing something with the database dumps they provide, although that's a last resort! But thanks for the feedback! I'll look through these issues in the next couple of days. :)
