I have noticed that if I enter more than one search term in the advanced Forum search, the search always does an OR search even if the two words are in quotes. I would like to be able to do AND searches. (For example NASA & shuttle would find only messages that have both the word "NASA" AND the word "shuttle". I would also like to be able to search for "Harrry Potter" and find only messages with the phrase "Harry Potter" in them. When I tried it today, the search function found messages that contained just "Harry".

Can I make the search function do what I want?
