Tag searching methods

A bit of a noob question, I'll admit, but what are some ways to better refine a search? Like for instance, you want to search for swimsuit pics, but only want the ones with yuri in it or something... how would you go about putting that in the search line?

Then you would search: swimsuit yuri.

Yay for being a noob! xD Thanks.

Just one thing to remember; if you are searching for a tag such as white hair, remember to use white_hair. Otherwise it would try to search for white and hair which would probably come up with nothing.

Also, it's reliant on the tags a person put on the pics. So don't be shocked if you do the search a bit later and stuff suddenly shows up that didn't before.

ex: a pic of the cover of a gunslinger girl manga may be tagged with "gunslinger_girl" and "henrietta", so searching for "guns" or "brown_hair" won't make it show up. But some good soul may add those tags when he sees they're not there.

Happens to me a lot.
