Checking MGNLDAM-1016, we detected that AssetListDataProvider.fetchFromBackEnd is called 4 times for each search as we can see in this video -> https://drive.google.com/file/d/1JEEormcz7dtmFn3cDaeDj9ttqu69t1Dl/view?usp=sharing

There are, in fact, 2 different searches all coming from vaddin. I don't understand why vaadin triggers the same search twice. And each search request produces 2 fetchFromBackEnd, one for obtaining the size of the result and another for the content.

As an improvement, we could temporary cache the result of fetchFromBackEnd, so there will only really be 1 fetchFromBackEnd request.
