Another annoying snag is that if you search for "A B", google will also search for "AB" (eliminating the space). This affects a lot of searches with acronyms and technical terms. For example, if you're looking for info on MIT's RAs, the top search results for "ra mit" or "mit ra" are related to "ramit" or "mitra".

This seems to be an optimization for their average user, but is really inconvenient for people searching for system errors, mathematical/cs theory terms, or other queries where acronyms are common.
