Since it does not matter for you, which column satisfies your criterion, the simplest way I can see is to concatenate all the columns like this:
SELECT *
FROM t1
WHERE CONCAT(id, f_name, l_name, .....) LIKE '%criteria%'
The above query will be equivalent to specifying many LIKE conditions with OR operator. Moreover, it will avoid errors in case your columns are of different datatypes, because CONCAT makes automatic conversion
