I disagree about the quality of Google search but I should note this has nothing to do with the utility of Google's vector search library, which is just one low level part of the process of creating a final Google and I'd expect the technical quality here to be excellent by default. Whether one likes or hates current Google search results, their qualities and the changes from early search processes are clearly intentional and don't relate to how well Google does raw indexing.
