How to Choose and Use Databases

Search well.

Connectors | Boolean Operators

Boolean operators connect your search words.  There are three of them. 


AND

Both cat AND dog must appear in the results.

Narrows the search.

OR
Results will contain the words cat OR dog (OR both OR neither). Broadens the search.

NOT
Results will contain cat but NOT dog. Narrows the search.

When searching databases,  it's extremely important that you connect your synonyms within the search boxes with ORs.  Do not use the OR from the pull down on the left; this'll make a huge mess of your search.  Only use AND, NOT from the left pull-down.   Keeping the ORs within the search boxes will ensure that your boolean operators are executed in the proper order.
