> Apart from search, ANNs can be use for recommendations, classification, and other information retrieval problems.
Yeah, those are all good use cases. I was wondering about a different thing: will the demand for a distributed vector search service concentrate to a few big companies, as smaller companies can use a simpler solution so they don't really need to pay for the technology.
> Currently, ES and Solr, both based on Lucene, can't really manage vector representations, as they are mainly based on inverted indexes to n-grams.
ES has kNN plugin, which stores vectors separately in each segment in Lucene index. Plus, they can also use better storage formats and algorithms.
