| Abstract | Information Retrieval Systems (IR) is using different indexing techniques to retrieve information such as, Inverted files, and Signature files. However, Signature files are suitable for small IR systems due to its slow response, while inverted file have better response time but its space overhead is high. Moreover, inverted files use B±trees for single-word queries. In this paper, a new indexing structure called TB±tree to be used in the design of inverted files for large information retrieval systems. The TB±tree is a variant of the B±tree that supports single key-word queries and phrase queries efficiently. In TB±tree algorithms which represent each key-word stored in the index by a numeric value, and this numeric value can be used as encryption and inforce security. The numeric value for each keyword is stored in binary format, which may reduce the size of the index file by 19%. The records in TB±tree may be of variable length. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
