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 MaxQueryTimeslice entry is the maximum amount of query execution time for a single time slice.


Units: Milliseconds of CPU time
Default: 50
Range: 1 - 1000



If the number of active asynchronous queries is greater than the number of allowed query threads, a query is put back on the pending queue at the end of the time interval specified by the value of the MaxQueryTimeslice entry. The end of a time slice usually occurs only after a matching row is found for the query. For some queries, however, many rows may be examined before a match is found. In these cases, the time slice can be exceeded before the time is checked.
