Whenever I search for a combination of words, say, for a review of a certain book by typing the subject/title and author name, I get a huge list of posts with either the author's name or subject, or both. I only require posts that feature both, and it takes quite a long time to wade through all of them; and in this forum the number of irrelevant search results can be quite large (think about all those homework problems that only have the subject name! ). So, would it be possible to add a feature that would search for "All words," "Any of the words," and so on? Or are there any "tricks," other than using Google , that can filter posts that has all words?
