The results or/and ranges of search in the fields containing numbers can be setted with one slider (if the search result must be a number), or two sliders (if results are in the number range).
For now, if we select multiselect field for search, we have a choise: dropdown ot multiselect. In case the choosen field contains numbers it will be proofed on selecting and the possiblitiy to set the search field as the slider will be added.
