Vectara search works but cURL times out

Can you try with a timeout in the header like the following?

-H "grpc-timeout: 30S"

Also, I notice that you have set lambda to 1 which indicates that you are looking for only keyword-based search results. Keyword-based search results are generally slower than neural search. We are working on improving those.

From the Console:

Lambda ranges from 0 to 1. At the extremes, 0 will execute a search based solely on neural search and 1 will execute a search based solely on keyword-based search. Values in the range of 0.01 to 0.2 seem to work well for many cases.
