Optimizing fuzzy search in XML using efficient trie indexing structure

In a traditional keyword based search system over XML data, a user submit keyword query to the system and retrieves relevant answers. In keyword search system where the user has limited knowledge about the data. Our proposed method provides the following features: 1) Search as you type: It extends Auto complete by supporting queries with multiple keywords in XML data. 2) Fuzzy: It provides high-quality answers that have keywords matching query keywords approximately. 3) Efficient: An index structures can reduce the searching time. An effective ranking technique can identifies high quality results. This method achieves high search efficiency and result quality.
