1. Search Multiple Terms Simultaneously
You can search Facebook for two, three, four, or more things at once by adding the “|” sign (minus the quotation marks) between the terms. For example “MakeUseOf | Lifehacker” will give you the result pictured below. This way you can see results of terms you want to compare on a single page.

2. Specify Your Search
This may seem pretty obvious, but wait ’till I get there. You can display different types of results by clicking the categories listed to the left. OK, that was kind of obvious. Now note that the list also features an option to only search for posts by your friends or from everyone, i.e. all over Facebook.
And that’s where it gets interesting, as you can now filter the results by language and post types. This is perfect if you’re looking to hook up with people from a certain area or just find local information.

3. Facebook App: Advanced Search 2.2 Beta
Using Facebook apps you can fill a specific niche. The Advanced Search app improves your search options within Facebook. It adds several new categories and search options. For example you can search for applications and have the results sorted by ‘most fans’ or ‘relevance’.

4. Website: FacePinch
FacePinch is a real-time Facebook search engine. So if you’re wondering what is being said right now about say Justin Bieber, this is where you would find out. The site also keeps an eye on trending topics and popular searches.

To use either Facepinch or the following website, Openbook, you do not need to own a Facebook account. They are open to the public.
5. Website: Openbook
At Openbook you can basically do the same as on FacePinch, with one little difference. You can discriminate between updates from guys, girls, or all genders. So if you were interested in female opinion only, that would be the place to check it out.

The idea behind Openbook was to make people aware of what they put online and that there are consequences. Their tagline is “Facebook helps you connect and share with the people in your life. Whether you want to or not.” Next to it is a button that says “Learn why this is bad!”
