I would suggest looking at what google does. It allows and/or searches in a completely unobstrusive manner. I would use only one search field, with the following algo:
1. split on 'OR' 2. split on words 3. join on words with AND 4. join on words with OR I would definitely search on all fields in your table. In split on words you might want to take into account words in double-quotes. Also I would use LIKE everywhere.
