I'm not sure if either approach would improve the results. Searching the introductions in additions to the list of ingredients, will rank recipes higher, when the ingredients you were searching for, occur more often in the instructions. But a recipe isn't necessarily more relevant, because of its instructions are more verbose. I'm not sure if an AND function would add much benefit. Yes, at the moment only one of the given ingredients must be part of the cocktail, in order that it appears in the search result. But the search results are also sorted by relevance, so that cocktails that contain more of the searched ingredients are ranked higher, than cocktails that contain fewer of the searched ingredients.
