My org has a need to be able to search for documents based on the assigned ID value. When adding files to a library, there are given an internal ID. However, searching on this field yields unpredictable and errant results. For example: I have in my library over 100 documents. When I enter the search term "ID:42" - I get multiple files. I get ID 42, but also ID 40 and ID 2.
We thought the issue may be that the field is not associated with a managed property, but we're having difficulties in setting that up.
Anyone have any idea why the built-in field returns odd/errant results when searched???
