Store index files somewhere other than the program data folder
As a PI system administrator I want to specify where search index files are stored or make sure that the index files are not consuming space on an OS drive , so that I can manage/optimize the disk usage on my server machine.
Now that PI Vision 2020 has been released and no longer uses the search index, this work is now unnecessary. Therefore the status is updated to declined.

As others have pointed out in a different suggestion (linked below), the indexed search crawler isn't used just in PI Vision.
