Pros & cons
Algolia
Pros: Lowest-latency hosted search at developer-friendly pricing; NeuralSearch adds vector layer without sacrificing keyword speed.
Cons: Indexed-content-volume pricing scales aggressively; less suited to large enterprise corpora than Glean.
OpenSearch
Pros: searched not found
Cons: searched not found
