The efficient state of the art query retrieval systems cannot be implemented on the XML based storage but can implement on the RDBMS databases. Fuzzy type-ahead search is a new information access paradigm for XML based systems though not a new concept for RDBMS based systems. Operations involving the system searching the XML repositories on the fly as the user types in query keywords for producing results. In the XML storage fast querying and result generation is the vital aspect. Prior systems used LCA-based (Lowest Common Ancestors) algorithms for implementing fuzzy type-ahead search and minimal-cost tree based techniques for top-k results over XML data.
