We have the keyword search option turned on for our application and it has worked well for over 4 years. We use the “search only fields used by this view” option to keep things simple. This week we noticed that we can’t search by entering a number, the system just spins and never returns anything. We can search by entering alpha characters and it works normally.
Our situation seems to be exactly the same as described and was noticed yesterday. If we search using only numbers all we get is the spinner but if the search contains letters only, or even 1 letter the search will perform as expected.
