Server-side number filtering

Webix JS
#1

How can a large collection be filtered on the server side by a numeric field? I found documentation for numberFilter, but not serverNumberFilter.

#2

you can create own serverNumberFilter:

webix.ui.datafilter.serverNumberFilter = webix.extend({
    $server: true
}, webix.ui.datafilter.numberFilter);

or even use serverFilter as serverNumberFilter.

on the server side you will need to parse filter value to get compare operator and actual value.
