Beyond the basics with Elasticsearch

on YouTube ↗37m

" summary

Shows concrete tricks rather than promises: use Elasticsearch aggregations for trend detection that compare time slices, use the percolator to index queries for alerts, geo-mapping and language heuristics (match ≥ four language tokens), and use significant_terms plus sampling to build recommendations from ~500 similar users. Reports real scaling: CPU-bound percolation workloads reach millions of percolations across a few boxes with millisecond responses, and examples include combining field-value boosts, distance decay and randomization to push useful results to the top.
