Some shows do not appear when searching ongoing shows

When I search ongoing shows, some currently airing shows do not show up. Specifically, Good Partner and Are You the One do not show up in the search results when I search ongoing shows. I only noticed these two shows because I am currently watching them and I know they have not finished airing. Other shows could well be missing and I did not notice. I like to search ongoing shows to find New shows to watch, so it’s disappointing the search leaves out shows.
