THE INVENTION
The disclosed invention relates to an information engine supporting
both keyword searches and parametric searches. Keyword search engines are
typically used to search for data in unstructured documents, such as HTML
pages, Portable Document Format (PDF) pages, and word processor
documents. Parametric search engines, on the other hand, are typically used
to search through structured documents, such as databases, that contain
information formatted into predefined categories or fields. Parametric
searches often involve arithmetic comparison operators such as: “less than,”
“greater than,” and “equal to” (i.e., <, >, and =). The present invention
teaches a solution by introducing a middleware layer on top of a generic text
search solution that provides parametric search capabilities using traditional
keyword search engines (Specification 1-2).
Representative claim 1 is illustrative:
1. A method for enabling parametric searches on source data using a text
search engine, the method comprising:
extracting at least one data unit from the source data;
automatically translating the data unit into at least one keyword
parametric entry; and
storing the keyword parametric entry in a surrogate document at a
search engine server.
