Abstract :
In this paper, we present a new search index generation technique that collects fields of office documents which are previously mapped to XML schema elements, and generate an XML-based search index including document types, file locations and fields collected from the documents and their semantic notations. The search index allows users to effectively find the target documents by specifying the document type and field values collected from the documents. In order to allow the search index to be securely shared by many users, access control policy is unified into the search index. We also propose an algorithm that computes the answer of search query corresponding to access permission of the user.
