While databases cannot understand natural language, database searches can be made very precise using Boolean operators. Boolean operators tell databases exactly how you want your search terms combined for the optimal results. While there are only a few operators, they can be combined to create a very sophisticated search for increasingly complex research topics. The video below discusses this in detail as well as how to avoid some common pitfalls of database searching. If you prefer, skip to the text discussion beneath it.

See MIT Libraries service updates for the latest information on access to services, collections, and spaces. This is important because searching library databases is a bit different from searching Google. The techniques described in this section will enable you to quickly retrieve relevant information from the thousands of records in a database. When you search a database and do not get the results you expect, Ask Us for advice. Library staff are happy to help you find what you need.
