Joel Bernstein commented on SOLR-8337:
--------------------------------------
Currently the ReduceStream is referred to by *group* Streaming Expression
function. Now that we will be passing in a ReduceOperation it makes sense to
call this function *reduce*. For example the syntax would be:
{code}
reduce(
search(collection1,
q="*:*",
qt="/export",
fl="id,a_s,a_i,a_f",
sort="a_s asc, a_f asc"),
by="a_s",
operation(...))
{code}
> Add ReduceOperation Interface

> This is a very simple ticket to create new interface that extends the
> StreamOperation. The interface will be called the ReduceOperation.
> In the near future the ReducerStream will be changed to accept a
> ReduceOperation. This will allow users to pass in the specific reduce
> algorithm to the ReducerStream, making the ReducerStream much more powerful.
