default filters to previous search ( as shown on query params of the asp)

The filters starts empty the first time users goes to the screen, after he searches, it retuns to the same page with the correct results, and the url show all the search filters values, such as:

https://connectedbusinesses.co.il/job-offer?s=&asp_active=1&p_asid=2&p_asp_data=1&termset%5Bregion%5D%5B%5D=66574&customset%5B%5D=job-offer&filters_initial=1&filters_changed=0&qtranslate_lang=0&woo_currency=ILS&current_page_id=377050

but the filters are shown empty again, I would expect that the filters will be auto populate by the query string parameters ( the selected terms, search text etc. )

how can that be obtained?

it seems like in the code there is a function, that might does it: selectByOptions but it doesnt get used anywhere and no documentation either.
