I was looking for some recipes that used miso, and quite a lot of the recipes that turned up did not have any miso in them. The difference between a search for miso and one for "miso" is quite large.
The recipes without miso or similar pastes did all have some paste (tomato paste, shrimp paste) and beans. Could it be that miso is translated into bean paste, and the filter then looks for the words bean and paste seperately? If so, could this please be corrected so the filter looks for the two words combined? Still questionable, as not all bean paste is miso, but it still would be a big improvement.
