Boolean Search

Is there a way to make the search feature accept boolean operators? Basically when I run a search on two terms, I want to find A AND B, not A OR B.

Unfortunately, not at the moment.

The simple search, as you've noticed, doesn't allow you to require that any given term be present. It does, however, alter the ranking of the results depending on how many terms of the search matched against each item, which may be sufficient depending on your needs.

The advanced, field-specific search is an "AND"ed search by default, so specifying additional terms there will always narrow your result set, never grow it.
