feasible to exclude the column in this case? Or would it be better to not do 
that and have a next step where we let people choose for each condition if they 
want it in the result or not?
  
  Except in cases where that condition is joined with an "OR" to another 
condition. Or it is a column that removes exactly one value. And only if there 
is not another condition for that property. So it is possible to do, but it is 
not a simple change. So I would prefer to do it in a second step.

  I agree, but I would be afraid that it would make queries even more likely to 
time out. Even if you just change the example query above for only 3 humans to 
require labels, it already times out. Do we have any leads on improving the 
performance of resolving labels in the query service?
