Dennis Gove commented on SOLR-8918:
-----------------------------------
Have finally got this in a finalized state. The admin page allows you to select
whether you want an explanation with your results or just the results. The
explanation has four types of nodes: Stream Decorator, Stream Source, Graph
Source, and Datastore. Each type shows in a different color. For those with
color-blindness the type of stream is also available in the node hover. I've
also added a legend. I did not make the nodes clickable - am leaving that for
future work.
I'll be splitting this up into two tickets. This ticket will cover the admin
page changes and a new ticket will be added covering the changes on streaming
classes to return the explanation.

> Add to the admin page an ability to work with and view Streaming Expressions.
> This tab will appear under the Collection selection section and will work
> similarly to the Query tab. On this page the user will be able to enter a
> streaming expression for execution. The user can then execute the expression
> against the collection and view all the results as they are returned from the
> Stream handler. Along with this the user will be able to view the structure
> of the expression in a graph-like layout.
> If the user wishes to only view the expression structure without executing
> the expression the user will be able to click an "Explain" button which will
> show the structure. Included in the structure will be information about each
> node (the expression for that node).
