#solr
in
#elasticsearch
or
#opensearch
:

Relatedness Aggregation in Elasticsearch
While reading AI Powered Search (AIPS) by Trey Grainger et al., I learned about the relatedness aggregation in Solr. This is not directly available in Elasticsearch, so how can we use it?

Wrote some notes for my later self to match on SPLADE/doc2query like related keywords that are weighted and use those weights for ranking with

Mat is not on 🦋—posting on his behalf! It's time to revisit common assumptions in IR! Embeddings have improved drastically, but mainstream IR evals have stagnated since MSMARCO + BEIR. We ask: on private or tricky IR tasks, are rerankers better? Surely, reranking many docs is best?
