Date Thu, 12 Apr 2018 15:45:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-12209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16435803#comment-16435803

David Smiley commented on SOLR-12209:
-------------------------------------

Wouldn't we want this logic to "push down" to search()?  I know it's nice fo have a generic
capability but search() is a Solr search which is pageable.

> Currently the closest streaming expression that allows some sort of pagination is top.
> I propose we add a new streaming expression, which is based on the RankedStream class
to add offset to the stream. currently it can only be done in code by reading the stream
until the desired offset is reached.
> The new expression will be used as such:
> {{paging(rows=3, search(collection1, q="*:*", qt="/export", fl="id,a_s,a_i,a_f", sort="a_f
desc, a_i desc"), sort="a_f asc, a_i asc", start=100)}}
> {{this will offset the returned stream by 100 documents}}
>  
> [~joel.bernstein] what to you think?
