INVERTED INDEX SYSTEM AND METHOD FOR NUMERIC ATTRIBUTES

A system and method is provided for generating an inverted index and processing search queries using the inverted index. To increase efficiency for queries having multiple numeric range conditions, numeric attributes are tokenized into a plurality of tokens based on their binary value. The tokens become keys in the inverted index. A numeric range query is translated into a query on multiple tokens and combining two or more range queries on different attributes becomes a simple merge of document identification lists.
