In interesting thought. Currently there are: .index(data) --> returns index of data in Index, or raises error .query(string) --> brute force search, returns all matching records .search(match) --> binary search through table, returns all matching records 'index' and 'query' are supported by Tables, Lists, and Indexes; search (and now index_search) are only supported on Indexes. ~Ethan~
