CDR: Keyword Query Language
Overview
This document defines a keyword query language for use with Content Discovery & Retrieval (CDR) Search Component implementations. A keyword, in the context of a basic search, is one of the strings used to find matching content resources. It was popularized during the early days of search engine development, as it was not possible to send natural language queries to those search engines and find the desired sites. Searches typically gave the best results if only a few keywords were chosen and searched for. These keywords attempted to capture the essence of the topic in question on the basis that the keywords were likely to be present on all sites listed by the search engine.
This specification defines a common syntax, providing enough information for Search Service providers and consumers to create and use CDR-conformant Keyword Query Language Search Services.
This specification supports Intelligence Community Directive 501(ICD 501), Discovery, Dissemination or Retrieval of Information within the Intelligence Community, which establishes policies for (1) discovery, and (2) dissemination or retrieval of intelligence and intelligence-related information collected, or analysis produced by the Intelligence Community.
