Searching and simple operators
Quotation marks: you can specify the Google engine to search an expression composed of two or more words literally, by typing the search terms in quotes.
"Used cars" will search all sites containing the phrase "used cars" literally.
AND: By default Google launches search results in linking the words entered by the user using this operator. So the end result of a search without specifying anything or using the AND operator results will contain both the word list specified.
The search "cars AND occasion" or "used car" get the same results, a list of Web sites that contain the word car and the word time.
OR or symbol "|": If you want to specify that it is not necessary the appearance of the two words in each search result, but each of them separately, you must specify the OR operator between the terms to be met this criterion.
"OR hand cars" now will result in a list of Web sites containing the word car or occasion.
An operator -: to preclude the search results. Must be specified before the end to ignore in order to seek the results that do not contain the specified word.
"Car-chance" to seek Web sites that contain the word car but no time.
You can assign different operators to fields delimited with parentheses:
"(Car OR motorcycle) AND occasion" search all webs that contain the word car or bike and with either of these two is essential to appear once.
"Site: site_name words to search", search only in this site.
"Site: es.wikipedia.org math," searches for all pages containing the word "mathematics" in the web http://es.wikipedia.org
You can view a site even when not working by clicking on the "cache" that appears next to each of the search results.
If you put "define:" followed a word (eg define: Human body) seeks definitions and encyclopedic text on that topic.
Using "cache:" before a URL , we display the contents of the Google cache (this is useful at a time when for some reason an address is not reachable temporarily).
If you type "filetype:" followed by the extension of a file search for pages that contain the extension of that file. For example: university filetype: doc
