If you enter a multiple-word search and fail to enclose them in quotation marks, the program expects a conjunction. This means that it is expecting you to have the words "and," "or," or "not" between them. For example, 'game not children.'
There are three buttons to choose from in this box:
Phrase Treats the words you typed as a phrase, as if they had been entered in quotations.
Or Treats the words as if you had typed "or" between them.
And Treats the words as if you had typed "and" between them.
