        abstract = {In this paper, we design a central keyword semantic search based semantic extension scheme to improve the result delivery. Keywords may have a certain grammatical relationship among them which react the importance of keywords from the user’s perspective intuitively. However, the existing search techniques regard the search keywords as independent and unrelated. For the first time, we take the relation among query keywords into consideration and design a keyword weighting algorithm to show the importance of the distinction among them. By introducing the keyword weight to the search protocol design, the search results will be more in line with the users demand. On top of this, we further design a novel central keyword semantic extension ranked scheme. By extending the central query keyword instead of all keywords, our scheme makes a good tradeoff between the search functionality and efficiency. To better express the relevance between queries and files, we further introduce the TF-IDF rule when building trapdoors and the index. Experiments on the real-world dataset show that our proposed schemes are efficient, effective and secure},
