Basic search adds some special features in order to increase the chances that a search will return relevant results.

Basic search has several characteristics:

• In basic search, if a user search query causes syntax errors in Internet Style mode or query operators mode, it is automatically retried in Bag of Words mode to be as forgiving as possible of user error. For example, if you enter dog and, this query would cause a syntax error in Query Operators mode, because it is missing the right-hand operand to and. The query would then be passed to Bag of Words mode, which would attach no special operator significance and would therefore retrieve documents containing dog and and.
• Term proximity can boost the relevancy ranking in basic search.
• Automatic spelling correction is applied only in basic search.
