on a SP2013 on Prem I have a two task lists, one is the working list, one is the archive. There is a simple workflow, that copies a task from the working list to the archive list, and than removes the item in the working list. It works fine, BUT even when the incremental crawl runs several times, the deleted item is still in the search index.
When I delete the task in the browser by hand, after the next incremental crawl the item is not found by the search.
Can anyone explain the difference or give me a hint, how to update the workflow, so that the search index will have the correct content?
