Thanks, the following qyery worked
/bjqfacet?q={!parent which=doc_type_s:parentDocument
score=min}+doc_type_s:middleDocument^=0 +{!parent
which=doc_type_s:middleDocument score=min
v=$priceRef}&priceRef=doc_type_s:childDocument^=0 AND
{!func}price_d&fl=*,[docid],score&sort=score
asc&child.facet.field=child_doc_field&child.facet.field=middle_doc_field
Result is sorted by min price.
But now I do not get child_doc_field facets. I need both child_doc_field and
middle_doc_field facets. How to do it better?
Thank you.
