Note Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client side search and Microsoft Search Server Express for server side search.
The MinMergeIdleTime entry is the minimum percentage of CPU processing time that must be idle during a merge-check period before Indexing Service can initiate an annealing merge.
|Range:||10 - 100|
Indexing Service uses the value of the MinMergeIdleTime entry to delay merges until there are no other heavy demands on the processor.
