UI Improvement

As you see the image, the search parameters are taking half of the page. Is there a way to reduce it or optimize the look?

I assume you’re looking more for design ideas than technical solutions?

Assuming that all the fields are of importance and you do not want remove then, the obvious thing that comes to mind is to add a button to toggle the parameters part visibility to make more room for Grid. In addition to that it could be possible to programmatically minimize parameter layout when focus is moved to Grid.

big search/filter UIs are often easier to fit into a vertical column next to the Grid (or whatever displays the results), rather than above it

Yes I close the accordion once the user click on the go button

But still the UI is not looking professionally right. May be if I see some visuals I can mimic it
