Correct, you can't do OR statements with tags.
However the "Keyword" field does search the "Tags" field so you can enter your search into the "Keyword" field like this: "Body oil"|"Bodybutter".
That should get you in the ballpark. Filter by merchant and price to further narrow your search if necessary.
