Doesn't filter &tvFilters in pdoResources value below 100?

Question

MODX

&tvFilters=
`square<=100` or `square>=1,square<=100` - doesn't work
`square>=100,square<=150` - works
square has the value (output):
92, 123.2, 150.5 etc.
What is the problem?

Answer 1

It works like this:
&where=`["TVsquare.value < 100"]`

Answer 2

getResources or pdoResources?
