The SELECT would examine more than MAX_JOIN_SIZE rows

I have a (fairly) complicated lookup query which uses up to 5 additional recordset filters on my product detail page, which is used to add product options when the add to cart button is pressed.

The page is responsive and causes no problems, but when uploaded to my hosting provider, i get the following error when pressing the add to cart button

The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is okay

I have added the line mysql_query('SET SQL_BIG_SELECTS=1'); to my page, and this overcomes the issue, but wondered how I could check for MAX JOIN SIZE ?
