Vespa seems like a great match for Elastic's text and vector search, but not for classic "OLTP"-style queries. For example, until very recently Vespa did not even have case-sensitive string field matching [1]; doing a strict equality query on a string field was not possible, and the authors did not seem to see why it would be useful. Vespa lacks a lot of this kind of basic search functionality, making it less general-purpose than Elasticsearch. It's clear that it's a very powerful search engine, though it also feels antiquated in many ways. It's very obvious that it's an ancient project that has been worked on by many different people throughout the years, with no cohesive vision or design, though it does seem like they're slowly cleaning things up. (The documentation used to be much worse, for one.) [1] https://github.com/vespa-engine/vespa/issues/10991 https://github.com/vespa-engine/vespa/issues/10991
