Abstract

A method and system for searching numerical terms are provided. The method includes processing a numerical term to a stem, the stem being in the form of a number, and a distance measurement of the numerical term to the stem, wherein a numerical term is a string of characters identified as a number by a numeric parser, and indexing the numerical term in a search index by the stem for search retrieval. The method includes receiving a query and processing the query to divide it into terms, including a numerical term. The numerical terms of the query are also processed to a stem and a distance measurement and document results are retrieved for the stem from an index.
