Search Techniques

While searching using natural language is commonplace with online search interfaces, understanding traditional power search techniques will help demystify your search results.

Boolean Logic

Phrase Searching

Guarantees that a string of words will appear together and in the order typed.  Most search engines require quotation marks (“ ”).

-- Also known as the exact phrase in advanced search mode

Example: violence commited by children

   

     

It is common for search engines to search all words in the phrase, though not exact phrasing.

Truncation or Stemming

Searches for multiple forms of a word. Generally the astrisk * is used following the root of the word.

Example: Terror* -- terrorist, terrorists, terrorism, terrorizing

Google automatically searches with trucation/stemming. Adding an astrisk does NOT work to search multiple forms of a word. Use a ~ to find synonyms

Sometimes this can be too vague:

Example: nav* -- how can you use the tools above to create a better search? 

Search Tricks

Try domain specific searches

Identifying the source of the information will be more relevant & more specific

Shortcut - site:.mil

Try format specific searches 

If you are looking for reports, PDF documents often have more content and are more focused

Shortcut - filetype:pdf

 

Try limiting the date range

If you are looking for current information, limit to the past week/month/year, or set range.
