Search queries to a search engine are collected over a period of time and used as a source of terms for selectively adding to documents. The terms may be added as meta-tags for enhancing information retrieval. Also, candidate terms may be submitted to the search engine and the most relevant documents retrieved. These documents, or portions thereof, are reviewed to determine if the content is substantially related to the term. If it is, the term is added to the document as a meta-tag and the search engine index is updated to reflect the addition. Employing this invention, search engine results will adapt to changes in usage of search terms.
