Apologies: there is some information on Boolean searches in our Search and Browse FAQ (http://archiveofourown.org/archive_faqs/13), though as ruuger notes this post is a bit more comprehensive. (The post itself is actually adapted from an older post (http://archiveofourown.org/admin_posts/160), which is linked in our Tutorials (http://archiveofourown.org/archive_faqs/25) section but should really be linked from the Search FAQ as well). We're currently working on updating all the FAQs so we'll make sure this information is incorporated more clearly.
If there's ever information you can't find, or some feature you'd like to see (or think must exist if you could only find it), please do get in touch with AO3 Support (http://ao3.org/support). With such a big site which is still in active development, it can be hard for us to keep up with documentation, and we're also aware our FAQs could be more navigable than they are (this is something we're working to improve right now). It's really helpful to us if you flag up gaps, and Support are more than happy to help.
