The answer is yes, of course. It has all the features required for an e-commerce search, inverted index and vectors included.
For a small to medium e-commerce site, a search plugin must provide great features, without too many headaches.
We cannot ask a site owner or a small agency to master tens to hundreds of concepts.
Can we make most of Vespa’s concepts invisible enough, without loosing too much flexibility and power?
This is what we are currently investigating: how Vespa’s architecture can be simplified to match the same features already integrated in our search plugin, with #elasticsearch or Weaviate, like: filter, facets, sort, analysers, vectorizers, vector similarity.
