A type of operator
used by some search engines
to improve search constraints by instructing the search to look for words that are within a short distance of each other in a document. For example, using a search engine that supports proximity operators, querying
the phrase “cable NEAR modem” will instruct the search engine to look in documents for instances of the words “cable” and “modem” that are near
each other. Different search engines will specify different distances that the words must be within.
