Search engines on the Web have popularized the keyword-based search paradigm, while searching in databases users need to know a database schema and a query language. Keyword search techniques on the Web cannot directly be applied to databases because the data on the Internet and database are in different forms
they do well for keyword search strings such as "ocean'08 conference information", they are quite inadequate for searching against structured data such as "time- series ocean surface temperature or salinity levels in the Gulf of Mexico". Traditional search engines deploy various complex algorithms, take into account the
keyword queries through a standard search engine and receive up-to-date database information. The system was then tested to determine if it could return results that were similar to those submitted using SQL. We also looked at whether a standard search engine such as Google could actually index the database content
