The RequestTimeout entry is the amount of time a query client should wait before it returns a failure to connect to a named pipe instance in Indexing Service.
|Default:||10000 (10 seconds)|
|Range:||0 - 1000000000|
If Indexing Service is not running, the client immediately returns a failure to connect.
The value of an identically named entry under the Catalog subkey for a specific catalog cannot override the value of this entry.
