-
-        A simple search with more keywords will return documents whose default
-        text search fields contain the search strings together or separately.
-
-        >>> search(q='Tim apple') # Will match "tim" and "apple"
-
-        More complex searches require the boolean search operator.
-
-        Wildcard searches can be used to search for any words that start with
-        the search string.
-
-        >>> search(q="'Tim*'") # Return documents with words like Tim or Timothy)
-
-        Search terms can also be combined. Allowed operators are "and", "or",

-
-        >>> search(q="(and 'Tim' (field author 'John Smith'))", parser='structured')
