When searching databases, use AND, OR, and parentheses to focus your search.
The asterisk * symbol will search for all variations of a word. For example: intell* will search for intellect and intelligent and intellectual. Using quotes will force a phrase search--those exact words in that order.
Combine synonyms with OR and put them inside parentheses, like this:
(grasshopper OR locust OR caelifera) AND respiration
Here's another example:
("escherichia coli" OR E. coli) AND binary fission
Also, check the "help" menu of a database for options to use truncation or stemming. The use of a special character will allow to search word roots for variations and plurals. For example, searching with protist* will provide results for protist, protists, and protista
