# Display Filter Operators and Conditions

Basic mathematical comparison operators can be used in conjunction with variables to construct filtering conditions.

Symbol | Example | Description
--- | --- | ---
= | count(feature![h])=3 | Returns Views with exactly 3 features with a label ID of "h".
!= | count(match)!=0 | Returns Views where the number of found models is not equal to 0.
< > | feature[t]/score>0.9 | Returns Views where the feature "t" is found, and has a probability score greater than 90%.
<= | min(region/x)<=50 | Returns Views whose leftmost defective region is located, at most, 50 pixels away from the left image border.
>= | random>=0.8 | Returns approximately 80% of the Views.
in | not score in [0.28,0.43] | Returns Views whose score lies outside the [0.28,0.43] interval (where 0.28 = threshold 1, and 0.43 = threshold 2).
