Did you know that only two Open source Vector search engines are fit to e-commerce?

e-commerce search main features are filters and facets (aggregations).

While most of Vector search engines are now able to filter results with more or less complex syntax, it is surprising that only two are able to aggregate results:

– Yahoo Vespa

– SeMI Technologies Weaviate

(Please let me know in comments for others)

Can anyone imagine a semantic search that do not provide faceted results on the left, as invented and promoted by Amazon ?
