I have a search bar on this page - hidden link which I had created using toolset views. You can find this in the views named "new crp number".
The problem is that right now it searches the custom field "crp number" of post type crp renovator and what I want is that it should also search by the name (which is another field I have created under the same post type)
Unfortunately this won't be possible in the sense of having a single filter target 2 separate custom fields.
However a general text search can be added to the view that will be able to cover all your custom fields when you've searched for a particular text. This does require the addition of the relevanssi plugin in order to search through the custom fields.
