In return, the user obtains a list of businesses whose description contains these keywords, ordered by their distance from
between the DHT overlay and the semantic overlay to support the search of a keyword sequence. Its time cost is sublinear with the length of the keyword sequence. Analysis and experiments show that the DST-based search is fast, load-balanced, and useful in realizing an accurate content search on P2P networks.
Finding relevant documents in digital libraries has been a well studied problem in information retrieval. It is not uncommon to see users browsing digital collections without having a clear idea of the keyword search that they should perform.

documents with document-level access control. The effective and secure search is realized by incorporating metadata identifying document types, keyword definitions and access control information directly into a search index. Given a search query of an authorized user, a technique that generates SQL statements on the search
important role to help communicate cloud computing system components. Tree based data structures are also used as index to perform the search faster. Currently most of the cloud providers use the keyword based search. Multi-attribute search optimizes the search process and also performs the search faster. The paper proposes a
Set the date range to filter the displayed results. You can set a starting date, ending date or both. You can enter the dates manually or choose them from the calendar.
