Dynamic update of a web index

Systems and methods are provided for regularly updating a web index with new or updated content, such as meta words or meta streams, for a particular web page address, such as a URL. Web page addresses and associated updated information, such as meta words, meta streams, values, and locations in the web index for those meta words are received. In order to update a web index, which is used by search engines to search web documents, a document identification is retrieved and associated with the updated information. As information in the web index is stored by document identification and not by web page addresses, the document identification may replace the web page address. Each meta word received is matched with corresponding document identifications and associated updated information, which creates an inverted format of the information. The web index may now be updated and stored by the system.
