Re: GEO Search with large table is very slow

As Markus suggests, individual indexes makes sense in this case. The reason is that it can't really make use of more than one field in an index anyway. Plus, one index may be better than another depending on the constants.

Please provide
* SHOW CREATE TABLE tbl\G -- need to see types and index(es)
* SHOW TABLE STATUS LIKE 'tbl'\G
* EXPLAIN SELECT ...\G -- especially after adding indexes and trying different constants
and surround them with [ code ] and [ / code ]
