What do you like best about Vespa?For our use case in advertising, Vespa leaves Apache Lucene-based products in the dust: - High indexing throughput while searching - Very, very technical team - Best of the best technical support and guidance - Multiple times, discussions were had and the next day the idea was implemented Review collected by and hosted on G2.com.What do you dislike about Vespa?- Search is still costly - Improving ANN capabilities with ideas like DiskANN - Simplify schema configuration and testing - Lean in on more cloud native technologies Review collected by and hosted on G2.com.

What do you like best about Vespa?Vespa provides a comprehensive set of features you would look for in a search engine, particularly in more ranking capabilites (e.g. leveraging ML models) and performance than what Elasticsearch offers out of the box. They're also constantly making advancements in new capabilities that they offer a nice hybrid between vector databases and a conventional search engine. Particularly for our business problem at OkCupid of recommending potential matches to millions of other users based on a myriad of factors and ranking algorithms, Vespa was a great fit to not only meet those use cases, but improve our team's development and iteration workflows in our recs system. The Vespa team is also very active on Slack: https://vespatalk.slack.com/ssb/redirect and genuinely collaborative. In my case, we worked together with an engineer from their team who helped raise improvement changes into the engine to help us meet our use cases. Review collected by and hosted on G2.com.What do you dislike about Vespa?One of the challenges in the past was around documentation and general community knowledge and expertise. Their documentation has since gone through a substantial revamp Review collected by and hosted on G2.com.
