8. A computer-implemented method for facilitating full-text search, the method comprising: organizing data tokens associated with a database entry into a lexicographically-ordered set of data tokens; generating a token set based on a combination of at least two data tokens from the lexicographically-ordered set of data tokens; converting the token set into a multi-dimensional vector; storing the multi-dimensional vector in a multi-dimensional index such that the multi-dimensional vector is associated with the database entry; and generating a query range from the multi-dimensional vector, wherein the query range includes a lower bound and an upper bound.
13. The method of claim 8 , wherein the token set includes four data tokens and the multi-dimensional vector is a four-dimensional vector associated with a token pair, a latitude value, and a longitude value.
