That maybe true Euler but Match Odds AND English Championship returns nothing while Match Odds and Championship returns Japan U19 v Mongolia U19 and Dundee Utd v St Mirren. Improvements would be useful. The existing selection criteria are useful but hit and miss. Also it requires individual multiple drag and drops which is tedious and could be avoided.
One thing that is useful that some users may be unaware of is that the existing search facility allows negative boolean selection. i.e. Match Odds AND Championship AND NOT Both teams to score.
NOTE: A quick update on this: to select Championship Match Odds for Saturday 4th November the following search criteria works! Then I only need to click the add button to add required English Championship Match Odds markets. (Obviously it will also have to be adapted in future if other competitions suddenly meet the "Championship" term)
"Championship AND Match Odds AND Soccer AND NOT Both teams to score AND NOT U19 AND NOT Scottish AND NOT 2.5"
