XML documents are semi-structured databases that maintain the document and content description. XPath and XQuery query languages are used to query XML data. XQuery is fairly complicated to understand its structure. Query languages require the knowledge about the document schema. Keyword based search models does not requires the prior knowledge about the XML document structure. Searching XML documents is achieved in different ways. In keyword query model search query keyword is passed to the system to fetch the relevant documents. Fuzzy type-ahead search in XML data scheme is applied to search XML documents with query keyword. Auto-complete and auto-correction methods are used to submit query keywords.
