Please change to only put this limitation only on 'Match all' queries, since the current implementation limits queries for any diagnosis in a certain block in ICD-10, which would still be a useful query to do.

There also is an inconsistency in how things work. If I select an entire block but that is more than fifty terms the user interface still shows the entire block as selected, but if I open the block I see that only part of them are selected. This leads to people thinking that they still searched the entire block. I think it is useful to make it visible in some way that not all of that block was selected next to the message at the top. At least it should only have the partial selection (-) symbol instead of the full selection (✓)
