Patent ID: 8332422

Claim:
A method for enabling parametric searches on source data using a text search engine, the method comprising: extracting at least one numeric data unit from the source data; automatically translating the numeric data unit into at least one keyword parametric entry; storing the keyword parametric entry in a surrogate document at a search engine server; receiving a parametric query from a client, the parametric query forming an attribute-value pair; automatically translating the parametric query into at least one keyword search entry, the keyword search entry forming at least one attribute-operator-interval triplet based on the parametric query; searching the surrogate document for the keyword search entry; and submitting to the client at least one result of searching the surrogate document for the keyword search entry; and wherein translating the parametric query into the keyword search entry includes determining at least one search interval; and wherein the operator is based on the search interval.
