BoboIndexReader and IndexReader: can Bobo be used for simple text search, just like IndexReader?

[EyalIsr]

I'm only starting to test BoboBrowse.Net, and would like to use it with minimum code changes to my existing Lucene.net code. So, I have 2 questions:

1. Can BoboBrowse.Net can be used to search for multi fields search as I use currently? that is, category:shoes color:white price:[100 to 150] kind of way.
2. Assuming the answer for my first question is YES, I would like to hear from some experienced users: should expect overhead (in terms of search time) if I use Bobo vs. plain old Lucene?
