: What I wanted is that 'albino' 'elephant' words have to appear in both
: 'text' and 'features' fields and optionally in 'name' and 'manu' fields.
there's no way to do that right now in dismax ... i actually don't think
there's anyway to do that in the underlying DisjunctionMaxQuery class --
the dismaxhanderl builds one for each of the words (and combines them all
into a BooleanQuery) but the "albino" DisjunctionMaxQuery for example
doesn't have any way to model that you want the "text" and "features"
clauses to be required. (DisjunctionMaxQuery doesn't have the
mandatory/optional/prohibited notions that BooleanQuery has)
Ok, I understand, thank you for your clear answer.
