Gus Heck commented on SOLR-17158:
---------------------------------
{quote}FYI, it was necessary to add this parameter in SOLR-17172, I used
{{partialResults=true}} to mean that we should stop processing and return
partial results with "success" code and "partialResults" flag in the response,
and {{partialResults=false}} to mean that we should throw an exception and
discard any partial results.
{quote}
I agree that the request should have a parameter to control this behavior as
well as providing a syprop to determine the result. I am setting it up such
that the parameter takes precedence over the syprop which only determines
default behavior if the parameter is not supplied. May be a complicated merge.
I've got things like this
{code:java}
if (thereArePartialResults && !rb.req.shouldDiscardPartials()) { {code}
That method will want to be use everywhere because it encapsulates logic for
both syprop and params.

> Project: Solr
> Issue Type: Sub-task
> Components: Query Limits
> Reporter: Andrzej Bialecki
> Assignee: Gus Heck
> Priority: Major
>
> Solr should make sure that when query limits are reached and partial results
> are not needed (and not wanted) then both the processing in shards and in the
> query coordinator should be terminated as quickly as possible, and Solr
> should minimize wasted resources spent on eg. returning data from the
> remaining shards, merging responses in the coordinator, or returning any data
> back to the user.
