Adddisjunctivefacet inside ais-index?

Hi all

I would like to call helper.addDisjunctiveFacetRefinement('allowedOrgs', ['PUBLIC']); in the search-function of ais-instant-search

the pb is that we have 2 tabs, and each of them use a ais-index element
because of that, it seems that the helper mentionned above cannot access the context of thoses ais-index elements

I get the following error:

allowedOrgs is not defined in the disjunctiveFacets attribute of the helper configuration

I f i try to use allowedOrgs as a facet with ais-refinement-list, it works properly.

Thanks in advance, for your help,

St├ęphane.
