Reflects the state of the current activities of Indexing Service, including merges, scans, and performance indicators on the computer running the service.

Constant/value Description
CI_STATE_ANNEALING_MERGE
0x8

 Some documents in the index have changed and Indexing Service needs to determine which have been added, changed, or deleted.
CI_STATE_HIGH_IO
0x100
 The level of input/output (I/O) activity on the computer running Indexing Service is relatively high. The threshold for entering this state depends on the value of the MaxWordlistIo registry entry. In this state, indexing is paused, but queries continue to be accepted.

0x40
 The catalog is in the process of being merged for the purpose of migrating the catalog.
CI_STATE_LOW_MEMORY
0x80

CI_STATE_MASTER_MERGE
0x2
 A master merge is in process.
CI_STATE_MASTER_MERGE_PAUSED
0x200
 The master merge that was in progress has been paused.

CI_STATE_SCANNING
0x10
 A scan is in process.

CI_STATE_USER_ACTIVE
0x1000
 The service is paused due to high activity by the user (keyboard or mouse). The threshold for entering this state depends on the value of the WordlistUserIdle registry entry. In this state, indexing is paused, but queries are still accepted.
