Information Retrieval (IR) expert parameters

The following table lists the startup parameters you can set from the Service Manager server's OS command prompt or from the Service Manager initialization file (sm.ini).

These parameters determine how Service Manager indexes and retrieves information using IR Expert.

Startup parameter Brief description
Information Retrieval (IR) expert parameters: ir_asynchronous Defines whether the Service Manager server immediately updates information retrieval files (synchronously) or whether the server creates a schedule record to process the files (asynchronously)
Information Retrieval (IR) expert parameters: ir_autostop Defines whether the Service Manager server stops an Information Retrieval (IR) search when a search term appears in more than 500 documents
Information Retrieval (IR) expert parameters: ir_boost_same_sequence Defines whether the Service Manager server increases the search weighting boost for documents that match the query term sequence
Information Retrieval (IR) expert parameters: ir_cluster_closeness Defines the percentage record similarity variance that records can have in an Information Retrieval search.
Information Retrieval (IR) expert parameters: ir_cluster_symbol Defines the alphanumeric character that indicates that the system should perform a clustered query.
Information Retrieval (IR) expert parameters: ir_disable Allows you to disable the IR keys on your existing Service Manager system, so that the upgrade process runs faster
Information Retrieval (IR) expert parameters: ir_language Defines the language of the text that you want Information Retrieval to index
Information Retrieval (IR) expert parameters: ir_languagefiles_path Defines the path to Information Retrieval language files that contain stop words, the stem dictionary, the suffix dictionary, and the normal dictionary
Information Retrieval (IR) expert parameters: ir_max_clusters Defines the maximum number of clusters to return in an Information Retrieval search
Information Retrieval (IR) expert parameters: ir_max_relevant_answers Defines the maximum number of relevant records an Information Retrieval search can return
Information Retrieval (IR) expert parameters: ir_max_shared Defines the maximum bytes of shared storage that you want IR Expert to use
Information Retrieval (IR) expert parameters: ir_min_cluster_members Defines the minimum number of records that Service Manager allows in any one cluster
Information Retrieval (IR) expert parameters: ir_minidf Defines the minimum relevance ranking that search terms must have for Service Manager to include them in Information Retrieval (IR) search results
Information Retrieval (IR) expert parameters: ir_opt_path Defines the IR option file path for the morphological analyzer.
Information Retrieval (IR) expert parameters: ir_prefix Defines the path to the Information Retrieval (IR) database files that contain the index
Information Retrieval (IR) expert parameters: ir_query_drop_off Defines the maximum percentage deviation from the original search term Service Manager can use to find related records
Information Retrieval (IR) expert parameters: ir_sql_limit Determines how many records are fetched from an RDBMS in a combined IR and SQL query
Information Retrieval (IR) expert parameters: ir_term_drop_off Defines the maximum percentage frequency that search terms can have in the Information Retrieval (IR) index for Service Manager to include them in search results
Information Retrieval (IR) expert parameters: ir_timelimit Defines the maximum number of seconds that an Information Retrieval (IR) query can run
