Tech Scholar, Department of Computer Science Engineering, Maharashtra Institute of Technology (MIT), Aurangabad, Maharashtra, India 2 Assistant Professor, Department of Computer Science Engineering, Maharashtra Institute of Technology (MIT), Aurangabad, Maharashtra, India Abstract Keyword search is the most effective information discovery method in documents. The large volume of data is stored in databases. Plain text coexists with structured data, unstructured data for this type of data efficient processing of top-k queries is a crucial requirement. This paper describes fundamental characteristics including relational database, top-k queries, steiner trees. Recently, Tuple units are used to improve the keyword search by joining the multiple related tuple units and indexes are used for structural relationships. In this paper various existing techniques for developing search system are compared. This survey also describes the Ranking. Ranking queries are dominant in many emerging applications for finding top-k answers. The research strategy used to resolve is top-k query processing. Key Words: Keyword Search, Top-k Query Processing, Relational Databases, Tuple Units. --------------------------------------------------------------------***---------------------------------------------------------------------- 1.
