Thanks Gavin for your pointers. I am in the waiting list for the search tool
you mentioned. I will continue to search on google in the meanwhile. Mans

Not to be dismissive, but one thing I've done that has been helpful for me,
is to search all public repos for usage/examples of the thing I am trying
to understand.
For example, this "RawQueryable" does not appear to be utilized in any
user-facing code on Github, so it may not be useful for you:
https://cs.github.com/?q=rawqueryable%20language%3AJava&scopeName=All%20repos&scope=
However, take something like "CalciteConnection" or "RelNode", try to
remove the Calcite repo itself, and you'll get a lot of hits and usage
examples:
https://cs.github.com/?scopeName=All+repos&scope=&q=CalciteConnection+%28NOT+path%3A%22calcite%2F%22%29
(I find that searching Scala repos usually gives more relevant results, due
to lots of Java results being duplicates)
This isn't nearly as good as getting a direct answer, but sometimes you
might be able to find what you're looking for
