Implement a checkpoint system for index crawls
When the crawler fails on an incremental crawl, the index search must perform a complete rebuild of the index. It would be beneficial for there to be a way to revert to a previous built index just prior to the failed incremental crawl so that the index file is available. This is particularly useful for large data sources that take hours or days to crawl before they're usable again.
Now that PI Vision 2020 has been released and no longer uses the crawler, this work is now unnecessary. Therefore the status is updated to declined.

The usage of PI Web API Search is not limited to PI Vision, it can also be used by custom applications or even custom PI Vision symbols.

Are there any plans to replace the search controller in PI Web API? This feature is still useful for indexed search in web API
