Title Search: Google does not use a controlled vocabulary, though that would be nice. But you can search by title of website. To do this, use the
"intitle:"
modifier.
Example: intitle:"Boston Common"
Explicit Phrase: Lets say you are looking for content about internet marketing. Instead of just typing internet marketing
into the Google search box, you will likely be better off searching
explicitly for the phrase. To do this, simply enclose the search phrase
within double quotes.
Example: "Boston unemployment"
Exclude Words: Lets say you want to search for content about internet marketing, but you want to exclude any results that contain the term advertising. To do this, simply use the "-" sign in front of the word you want to exclude.
Example Search: "Boston unemployment" -"service industry"
Site Specific Search: Often, you want to search a
specific website for content that matches a certain phrase. Even if
the site doesn’t support a built-in search feature, you can use Google
to search the site for your term. Simply use the "site:somesite.com"
modifier. Note the "+". Forces Google to search for the word exactly as is.
Example: +Boston site:www.usa.gov
Similar Words and Synonyms: Let’s say you are
want to include a word in your search, but want to include results that
contain similar words or synonyms. To do this, use the "~" in front of
the word.
Example: +Boston ~labor
Specific Document Types: If you’re looking to
find results that are of a specific type, you can use the modifier
"filetype:". For example, you might want to find only PowerPoint
presentations related to internet marketing.
Example: "Boston history" filetype:ppt
This OR That: By default, when you do a search,
Google will include all the terms specified in the search. If you are
looking for any one of one or more terms to match, then you can use the
OR operator. (Note: The OR has to be capitalized).
