1. One or more computer-readable non-transitory storage media embodying software that is operable when executed by one or more computing devices to:
- derive a concept matrix from a plurality of sample documents using singular value decomposition of a term-document matrix, the concept matrix identifying a latent pattern of word usage in the plurality of sample documents around a concept;
derive concept terms by extracting significant terms from search text and inferring relevant terms therefrom in accordance with the concept matrix; and
generate a query comprising a search expression having at least one of the derived concept terms.

Abstract
A concept bridge employable with a search engine, method of operating the same and computer information system employing the concept bridge and method. In one embodiment, the concept bridge includes an extractor configured to derive concept terms by extracting significant terms from search text and inferring relevant terms therefrom. The concept bridge also includes a query generator configured to generate a query consistent with an index of a search engine as a function of the concept terms.
