 Do you need to do this within a DB query (SQL), or is the "search" in-memory? Are there any other constraints on the problem space that might be used to simplify things? (E.g., are the ranges all exactly the same size? or a multiple of some size?) If you need to do significant numbers of checking at a time, then some pre-processing of the data while loading into memory is a good tradeoff. If these are one-off checks against the DB, then pre-processing is probably not worth it. A positive attitude may not solve every problem, but it will annoy enough people to be worth the effort.
