Text Multiple words can be entered with spaces. But the query will take it as a single word.
Two wild cards can also be used: (1) * for a string of characters; (2) ? for a single character. If * and ? were to be used as real characters, place "\" (backslash) before them.
For Keywords and Author fields these can be combined with AND and OR logical operations to form more complex patterns.
