Information Retrieval (IR) expert parameters: ir_autostop

Parameter

ir_autostop

Description

This parameter defines whether the Service Manager server stops an Information Retrieval (IR) search when a search term appears in more than 500 documents. When enabled, IR considers a term irrelevant and stops tracking it when the term appears in more than 500 documents. However, those 500 index entries remain in the system.

By allowing IR to automatically stop terms, the size of the IR files is limited, and the performance of IR improves. If you do not use the autostop feature then you should make sure that terms that are frequently used but that are of no interest in retrievals are placed in the IR stop file.
