Description

Positions will be first class citizens rather sooner than later. We should explore proximity scoring possibilities as well as collection / scoring algorithms like proposed on #3952 (2 phase collection)

This paper might provide some basis for actual scoring implementation: http://plg.uwaterloo.ca/\~claclark/sigir2006_term_proximity.pdf

Research direction

Start by reading the parent issue #3952 and the linked term-proximity paper. Review the proposed two-phase collection and scoring possibilities, then clarify which proximity-scoring behavior and collection algorithm should be implemented. Done should be a decided, testable implementation scope rather than an open-ended exploration.
