A simple solution that has very good documentation and low research consumption
LanceDB is deployed on-cloud in our organization. I have only utilized the community-specific version. They have a server-client version that might actually be useful for a lot of other people. I just needed the direct one, which works quite well for me. I don't know how good the server client version is yet. Overall, I rate LanceDB a nine out of ten.

Vector search has improved e‑commerce relevance but setup and learning curve still need work
Vespa definitely had its own set of challenges. It was really hard to get into initially, especially when I started implementing it in 2024 along with one junior employee, and the lack of documentation made it difficult. I aimed for an implementation with ColBERT, a sparse embedding mechanism, which I believed would fit well for e-commerce. We went through iterations during A/B testing because the initial set did not work as expected, which extended the process to about one and a half years. Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it. Community support was decent, and we turned to it for clarifications. However, substantial improvements in documentation are necessary, especially more examples for handling DSL effectively. Having a runtime testing feature would greatly facilitate quick iterations.

What is your experience regarding pricing and costs for Vespa?
The setup cost is definitely huge, and pricing is also steep. In terms of licensing, it seems generous for those who do not want to engage with Vespa's hosted services.

What is your primary use case for Vespa?
My main use case for Vespa is implementing it as the back-end search engine for an e-commerce site, where we have about six million products, or six million SKUs, that we are selling. I implemented...
