Supercharging the Elasticsearch Percolator
- petard 11y agoWhat are your memory settings for utilizing the 360GB RAM with ElasticSearch?
- alxnlssn 11y agoCurrently running with three ES data nodes per physical machine, with 30GB -Xmx allocated to each instance.
- rchakra3 11y agoCan you explain how a positional query is a subset of boolean queries? Intuitively it feels like the reverse would be true.
- bergetp 11y agoYou're right, but the point here is that positional queries are boolean queries plus positions. For example, document that match 'a NEAR b' are a subset of documents matching 'a AND b'. So if 'a AND b' has no matches, there is no need to execute the more expensive 'a NEAR b'.
