Social Searcher site allows to search on Facebook without logging in. One may use any keywords to narrow down the search results around Facebook. It's really handy while searching for old friends and you don't remember a lot about them. Also Facebook still has no search engine at all and in build search is glitching very often.
According to the site information, Social Searcher is built upon combination of Google custom search and Facebook’s publicly available API.
Here are some Facebook Search tips for this service:
1. Phrase search (””)
By putting double quotes around a set of words, you are telling Facebook Search to consider the exact words in that exact order without any change. For example, search
“Obama Plans to Keep Estate Tax”
will find only facebook pages where this article from WSJ is shared.
2. Terms you want to exclude (-)
Attaching a minus sign immediately before a word indicates that you do not want pages that contain this word to appear in your results. The minus sign should appear immediately before the word and should be preceded with a space. For example, query
Cars in USA -Chevrolet
will exclude all references to Chevrolet from the search result on Facebook.
3. The OR operator
Facebook Search’s default behavior is to consider all the words in a search. If you want to specifically allow either one of several words, you can use the OR operator (note that you have to type ‘OR’ in ALL CAPS). For example, query
Real estate in USA 2009 OR 2010
will give you results about either one of these years.
