Allow using methods with keyword arguments in search DSL with Ruby > 3

[andreslemik]

Example:

# ruby 3.2
def kwargs_method(first:, second:)
  [first, second]
end

Sunspot.search(Post) do
  with :some_field, kwargs_method(first: 1, second: 2) # with :some_field, [1,2]
end

Is there something that isn't backwards compatible with Ruby 2.x in here? Could we just use the new kwargs code for all versions?

[andreslemik]

You are right, this code should work with all 2.x versions. I checked it with version 2.7 and it works.
