You may use quotation marks:

" Double quotes around a phrase, matches only conceptions containing the complete phrase. For example: "mental mode" is different than just: mental model

You may also use a full set of boolean operators:

Place a + in front of a word to require it, - to exclude it
~ A leading tilde marks a word as less important. It's useful for marking noise words.
* An asterisk acts like a wildcard. Unlike the others it is placed AFTER the word and not before it.
( ) Parentheses are put around sub-expressions to give them higher precedence in the search.

For example you can search for:

  • mental model
  • "mental model"
  • +mental -model
  • (mental model) rhetoric
  • rhet*
