This value identifies the maximum size of a single file filtered with the default filter. If a file exceeds this size, only file properties are filtered. This limit does not apply to registered file types; that is, to those file types that do not use the default filter.

III-86 Value Name: MaxFilesizeMultiplier
Data Type: REG_DWORD
Value: 0x8

This value identifies the maximum amount of data that can be generated from a single file, based on its size. This value is a multiplier used in conjunction with the current file size to determine the maximum file size after content indexing. For example, a value of 2 means that a file can generate up to 2 times its size in content index data.

III-87 Value Name: MaxFreshCount
Data Type: REG_DWORD
Value: 0x4e20

This value identifies the maximum number of newly indexed files that cause a master merge to start.

III-88 Value Name: MaxIdealIndexes
Data Type: REG_DWORD
Value: 0x5

This value identifies the maximum number of indexes considered acceptable in an ideal system. If the number of indexes exceeds this value and the system is idle, an annealing merge brings the total count of indexes to this number.

III-89 Value Name: MaxIdealIndexes
Data Type: REG_DWORD
Value: 0x32

This value identifies the maximum number of persistent indexes in the catalog. If this number is exceeded, a shadow merge brings the total below this number.

III-90 Value Name: MaxMergeInterval
Data Type: REG_DWORD
Value: 0xa

This value identifies the sleep time between merges. Index Server often activates this to determine whether an annealing (most common), shadow, or master merge is necessary.

III-91 Value Name: MaxPendingDocuments
Data Type: REG_DWORD
Value: 0x20

This value identifies the maximum number of pending documents that are filtered before the content index is considered out-of-date for property queries.

III-92 Value Name: MaxQueryExecutionTime
Data Type: REG_DWORD
Value: 0x2710

This value identifies the maximum execution time of a query. If a query takes more than this amount of CPU time, its processing is stopped and an error is returned.

III-93 Value Name: MaxQueryTimeslice
Data Type: REG_DWORD
Value: 0x32

This value identifies the maximum time allowed for Index Server to execute a query in a single CPU time slice. If more asynchronous queries are active than allowed query threads, Index Server puts a query back in the pending queue after this time interval. CPU time slicing is performed only after a matching row is found, so the time spent in a time slice may overrun this and a considerable number of rows may be examined in the time slice.

III-94 Value Name: MaxQueueChunks
Data Type: REG_DWORD
Value: 0x14

This value identifies the maximum number of in-memory buffers (queue chunks) allotted to keep track of pending documents. The higher the number, the less frequently the memory buffers are written to disk.

III-95 Value Name: MaxRestrictionNodes
Data Type: REG_DWORD
Value: 0xfa

This value identifies the minimum number of restriction nodes created by query normalization. If this value is exceeded, the query fails with the status of QUERY_E_TOOCOMPLEX. This status message means the query was too complex to be completed because the limit imposed in this registry key was reached. This key keeps a user from overloading the server’s capacity with an overly large query.

III-96 Value Name: MaxShadowFreeForceMerge
Data Type: REG_SZ
Value: 0x1f4

When disk space occupied by the shadow indexes exceeds this value and the free space on the catalog disk drive falls below the MinDiskFreeForceMerge value, Index Server executes a master merge.

III-97 Value Name: MaxShadowIndexSize
Data Type: REG_DWORD
Value: 0xf

When the disk space occupied by the shadow indexes exceeds this percentage of the catalog drive, Index Server executes a master merge.

III-98 Value Name: MaxWordLists
Data Type: REG_DWORD
Value: 0x5

This value determines the maximum number of concurrent word lists that can exist.

III-99 Value Name: MaxWordlistSize
Data Type: REG_DWORD
Value: 0x5
