Using OR in LIKE Query in MySQL to compare multiple fields

I always thought that you could use OR in a LIKE statment to query things in MySQL. So, if I wanted to compare multiple fields in a row to 1 keyword or term:

SELECT * FROM MyTable WHERE Column1 OR Column2 LIKE '%keyword%'; 

and if I had an array of words to compare:

SELECT * FROM MyTable WHERE Column1 OR Column2 LIKE '%keyword1%' 
AND Column1 OR Column2 LIKE '%keyword2%';

I don't believe that syntax is correct, however. Is there an efficient method of writing this aside from something like:

SELECT * FROM MyTable WHERE Column1 LIKE '%keyword1%' OR Column2 LIKE 
'%keyword1%' AND Column1 LIKE '%keyword2%' OR Column2 LIKE '%keyword2%';

Am I going about this correctly?

Use this::

SELECT * FROM MyTable WHERE (Column1 LIKE '%keyword1%' OR Column2 LIKE 
'%keyword1%') AND (Column1 LIKE '%keyword2%' OR Column2 LIKE '%keyword2%');
