Googling Aliens

Although throughout much of a student's academic career they think that he or she knows how to use google. When trying to find internet  sources for a topic such as aliens, one has to know how to find something that is useable. Just googling aliens and one will retrieve results including the amount of aliens living in the United States, joe's alien sighting database, lots of videos of supposed alien encounters, but trying to find credible information will take several pages. Google, actually has limiters that most databases have, people just do not use them or know about them. One can limit the domain by adding to the search site:.org or site:.gov or whatever type of source one desires. This is particularly useful when searching for extraterrestrials. Using only this limiter I was able to find project blue book; which is the government study on aliens. I was also to find that the CIA keep track of supposed alien sightings and their reliability. On Google, one can also limit the location, date published, truncation also works with google. The best way to be able to fully take advantage of the Google advance search options and limiters is to use them and just mess around with them.
