Short Description: Specifies the number of indexing threads to use for Domain Search.
Specifies the number of indexing threads to use for Domain Search. Using more threads lets the Domain Catalog server index more files simultaneously, but requires more CPU utilization, and response to search queries may be slow. With fewer indexing threads, search speeds up because of greater CPU availability, but changes are not reflected in the index as quickly.
None, although if this setting is omitted, the default number of threads used is two per CPU. For example, a server with two CPUs uses four indexing threads by default when indexing.
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
