Most efficient way to search multiple tables for one value

Question

I'm trying to search for one value against 3 tables e.g.

user searches for 'test'

'test' needs to be a where clause for 3 tables. I could do it like:

SELECT * FROM `table1` WHERE `field` = "test";
SELECT * FROM `table2` WHERE `field` = "test";
SELECT * FROM `table3` WHERE `field` = "test";

but that seems like it could be simplified, any thoughts? Not searching information_schema for data.

Thanks
