The document discusses the purposes and uses of indexing in information retrieval systems. It defines indexing as constructing representations of documents to browse and maximize searching success while minimizing time and effort. Indexing facilitates reference to specific materials, acts as a filter for irrelevant information, and provides overviews of subject fields. The document then defines information retrieval as the selective and systematic recall of stored information. The purpose is to collect and organize information across subject areas. An information retrieval system consists of operations to index documents, store the resulting records, and retrieve them. It identifies six key functions: acquiring documents, analyzing content, representing content, coding indicators, storing documents and indicators separately, and developing and executing search strategies to disseminate results.

2. General Purposes of Indexing
• To construct representations, of documents in a form that
is suitable to the users to browse .
• To maximize the searching success of the users.
• To minimize the time and effort in finding information.

3. Use of Indexing
• Facilitate reference to the specific materials.
• Serve as filter to withhold irrelevant materials
• Make the information storage and retrieval
system useful.
• Disclose related information
• Provide a comprehensive overview of a subject
fields.

5. Information Retrieval
Selective, systematic recall of
logically stored information.

6. Purpose of Information Retrieval
Collect and organize information in
one or more subject areas.

7. Information Retrieval System
Set of operations, procedures by which
documentary units are indexed the resulting
records are stored and displayed and so can
be retrieved.

8. 6 Distinct Functions
(1) Acquisition of the necessary and appropriate documents.
(2) Preparation and representation of the content of those
documents.
(3) Coding of the content indicators.

9. (4) Organized storage of those documents and their indicators
in separate files.
(5) Development of operational search strategies .
(6) Physical dissemination of the retrieval results.
