In SharePoint Online, we have a list with about 3500 entries in it. However there are 193 Columns on this list so it's quite big/wide.
Recently the 'Find an Item' box has started to return incorrect results. If I search for a value I know would return 10 entries I'll only get 4 returned. Initially I thought my view was the issue but I've created an 'all items' view and this still only returns 4 items, not the 10 I know are there.
I know they are there because I can do Ctr-F on the page and put the same search in and they are all there. This is not an acceptable workaround for the users.
I've requested a re-index of the list and waited 24 hours but the issue remains. I've checked list settings and there is no approval required for entries and any user with 'Read' can see content.
It feels like the amount of Columns is making the 'Find an Item' Box struggle but I can't find anything online to point me in the right direction.
Any help greatly appreciated.
