Best How To :
You shouldn't use custom options for different sizes. This is why you have configurable products.
You make a configurable product and then link it to simple products which represent its sizes.
Then for the simple product you select visibility: search (to show it on search).
Custom product options are NOT used in search and there is nothing you can do to use them in search (apart from building a very complex module).
Another solution would be to put the values from the custom options inside an attribute which has
Use in Advanced Search and
Use in Quick Search to yes.
