LexiBot is a specialized search tool developed by BrightPlanet, as a means of searching the deep Web (the hidden part of the Web that may contain 500 times the content accessible to conventional search engines). LexiBot uses what BrightPlanet calls a comprehensive and intelligent search technology that enables users to conduct searches using simple text, natural language, or Boolean queries on hundreds of databases simultaneously, filter and analyze data, and publish the results as Web pages. LexiBot was designed to perform complex searches to identify and retrieve content from all areas of the Web, and to process the information.
Deep Web content has been accessible only to those who knew the correct URL for the Web site. Then, even once a user had connected to a database, its data could only be accessed by single direct queries. LexiBot acts as an automated direct query engine to make dozens of queries simultaneously to multiple databases. Searches are supported on close to 600 databases. Once the links are found, LexiBot downloads the links, analyzes them, removes the irrelevant ones, then downloads the text portions of the documents to the user's hard drive. The application can be used with desktop databases as well as the Internet, is customizable to user preferences, and can be set up for either simple or advanced usage.
