I am trying to understand population options for SQl server's full text indexes. My target is to access whether our currently used option (default = CHANGE_TRACKING AUTO) is the best to use in our case.
I think I have understood perfectly every bit of information in the related MS reference page, except from this devilish line from the subchapter Population based on change tracking/Enable change tracking/Automatic population:
...the tracked changes are propagated automatically. The full-text index is updated in the background, however, so propagated changes might not be reflected immediately in the index.
Nothing in the following reference, however, gives any information about what exactly
not immediately means in regards to the exact time the population happens. I have found around queries that can return the last timestamp the population took place; but how can I have an idea of how often and when the system tries to, or indeed executes, the population?
