- Architecture & Design
-
- The implementation of the SearchManager/2 Graphical User Interface
- follows the guidelines of the IBM SAA Common User Access (CUA) 91
- architecture.
-
- For client/server communication Named Pipes or TCP/IP can be used.
-
- The SearchManager/2 document index is a (fully) inverted index of
- the textual content of documents.
- The basic techniques are described in any reference book on Information
- Retrieval.
- SearchManager/2 implements a three-level index (vocabulary, document
- references, context information) to allow fast processing of simple
- queries (queries without explicit or implicit proximity operators).
-
- The vocabulary itself is indexed by a fragment index to allow fast
- resolution of masked words.
- The implementation uses a technique developed by the IBM Scientific
- Center in Heidelberg for STAIRS (called 'partial match retrieval').
-
- The SearchManager/2 vocabulary uses a (internal) universal code page
- to support multi-lingual environments.
