Custom taxonomy dropdown

Hi,

I’m using a dropdown with custom taxonomies, but the search results aren’t showing the right pages. In settings, I have selected the post type and the taxonomy to include in the index. The taxonomies are listed in the dropdown.

When I use a regular input search field, the search results are fine, but with a dropdown, they are showing pages unrelated to the keyword.
