We can live with all the limitations:
- no counts
- we don’t have sub-categories/facets
- the logic to ORed within a facet and ANDed across facets - seems logical
- We have organised ourselves out of gscope type.
However the zero result combination does seem like a serious limitation. Is this likely to be changed in the future?
The example aleks posted over at Changing Funnelback facets form control type - #4 by gavin1211 does a really nice job, with good behaviour.
