How The System Of Uris Should Be Designed?

The ListView should display the content of the rather long code-list of products (say up to 100 thousands, i.e. nothing small). Because of that, effective and interactive searching

Solution 1:

1. it is a matter of convenience how you structure it. I add "filter" URIs to reduce complexity of queries (e.g. multiple "WHERE" conditions, "JOIN"s)

2. ListView is reusing child views so it can handle much. Adapter filter is designed to reduce what is already in the adapter. As we are talking about large data I would prefer to not get it loaded in the first place.
