Hi,  
I would like to know how do I use the attribute “pyson\_search\_value” that is available on the action object passed in the state action functions on a wizard to filter the records that I want when the tree(list) is displayed. I tried using the similar syntax used for the pyson\_domain, i.e:

action[“pyson\_domain”] = PYSONEncoder().encode([(“party.id”, “=”, party.id), (“template.id”, “=”, product.id)])

But this didn’t work. I scan all the modules and trytond tests files and couldn’t find any examples of how and what is passed to pyson\_search\_value. The reason that I need to use a search instead of domain, is that the domain limits the choices to those used in the expression above when opening the tree that is editable for the user, while a search will not, at least that is my hypothesis.

It works the same way as the `domain` but it must be a domain that can be written in the search bar.  
So using id is not possible, using dot notation is only available on recent version (and limited to 1 level by default).
