1 search field to filter multiple lists on multiple properties

We want to be able to use 1 search field to filter multiple lists, on different properties.
Today, this is doable like this:

<solid-form-search
  id="search"
  fields="nameSet(hd_name, sib_name)"
></solid-form-search>

<solid-display
  data-src="hd.com/users"
  fields="nameSet(hd_name)"
  filtered-by="search"
></solid-display>

<solid-display
  data-src="sib.com/users"
  fields="nameSet(sib_name)"
  filtered-by="search"
></solid-display>

However, it feels strange to add sets to the lists to allow such a filtering because it changes the DOM structure. It may be easier to edit the solid-form-search to specify which fields should be used for filtering:

<solid-form-search
  id="search"
  fields="name"
  search-name="hd_name, sib_name"
></solid-form-search>

<solid-display
  data-src="hd.com/users"
  fields="hd_name"
  filtered-by="search"
></solid-display>

<solid-display
  data-src="sib.com/users"
  fields="sib_name"
  filtered-by="search"
></solid-display>

@balessan @clement what do you think?
