Filter input placeholder

Hey Meitar, I would like some quick help. I want to remove the label “Search:” from the left of the filter/search input and add the same label (Search) inside the input box as a placeholder. This will allow it to match the rest of my website’s input styling. I did some digging in the plugin files and I just couldn’t find where the plugin generates this. Can you help me out?
