airodyssey on "Search engine booleans"

Hi,

I browsed though the support documentation and did not find any help on how to search posts and pages on a specific blog through the search widget.

I have two specific questions:

• Can you include/exclude terms? On some search engines you can use booleans (AND, OR, NOT) or symbols (+ -), but I tried both and they don't work.
• Is there any way to specify, for example, to restrict the search to a specific category?

I did notice one thing though: using quotation marks to specify an exact phrase works wonders.

Thanks!
