Advanced Keyword Search (Complex query)

This search is for searches with 3 or more "minimum search units". If you are looking for exact match then just type them in with spaces in between. If complex logical operation is desired, you MUST use parentheses to group and prioritize the logical operations. In that scenario, there MUST be a logical operator between every two units.

Example 1: "Horse Race" AND money
Example 2: (Land OR Property) AND (Tax OR Regulation)
