I tried to predefine some of the parameters of the default search form, and got an error. I guess that we assume that all the parameters are defined if at least one is.

Go to https://localhost:8000/search?search[content_types][]=article&search[content_types][]=folder.

Notice: Undefined index: limit in vendor/ezsystems/ezplatform-search/src/lib/View/SearchListViewFilter.php (line 76)

The idea is to create a link to the search form that include some predefined filters.
