Hi,
I want to match and score on a sorted DocList.
The use case is something like this
- Cache sorted results (with scores) of certain queries in the
queryCache (This is a DocList)
- New queries are superset of these cached queries and have dynamic
scoring clauses
- At runtime, I want to lookup results in query Cache and run matching
and scoring on this list
- This enables me to have a more dynamic way (per query) of pre
sorted data set where I can early terminate shorter and more effectively
and reduce latencies even further
- In some cases, I can use the cached score along with new score too
and avoid recomputation here.
The problem is currently the Scorer interface requires a DocIdSetIterator
and can't work on top of a DocList.
So does that mean, enabling this kind of optimisation requires using a
different Scorer & Weight interfaces or is there something I can do using
the current interfaces itself ?
