About Basic Search Behavior
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.
