Solving the issue of Inconsistent search results and “disappearing” articles on Summon
We often find that identical searches performed on consecutive days come up with different numbers of results, and articles found when doing the search on one day don’t appear when doing the search on another day. The explanation we have been given is that it depends which server you hit with your search, but shouldn't the contents of each server be identical? This is especially problematic if you are running a workshop where students are completing a worksheet where they are asked to give numbers of results. The missing content is obviously an issue if you find something useful one day and it has gone the next.

This is also one our number one priority concern with the summon index. We are experiencing this issue for a long time and have made a ticket regarding this more than once.
Since we are loading our local data to the index and use summon as the only search instrument for our users this issue, from our point of view, cant be addressed enough.
