A Column to Identify Indexing Status
While Index Statistics show the number of Indexed, Partial, and Unindexed Files, an optional Column that shows the indexing status of Attached PDFs would be helpful. Say, for example, a string is known to be in a library, but it doesn't show up in a search. Readily seeing that a file is not indexed or only partially may be useful in tracking where the string is located. If that's not possible, then perhaps an expedient way to compile a list of the Index status of all files would be a second-best solution.
