[jira] [Comment Edited] (SOLR-13105) A visual guide to Solr Math
Expressions and Streaming Expressions
[ https://issues.apache.org/jira/browse/SOLR-13105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17259981#comment-17259981 ]

-------------------------------------------------------------------
This issue was completed enough for a version of it to be available for the last year or so at https://github.com/apache/lucene-solr/blob/visual-guide/solr/solr-ref-guide/src/math-expressions.adoc. There were a couple of obstacles to merging it with the Ref Guide:
# This new content includes a number of images, which would not have worked as well with the former design of the Guide. As of 8.6 a new page layout was introduced, which was in part designed for content such as this to image-rich content to use as much of the page as it needs.
# The visualizations use Apache Zeppelin and rely on a Zeppelin-Solr interpreter that is provided by Lucidworks in an open repo. Recent releases of Zeppelin have had a series of issues that made installing the interpreter problematic or even impossible. Those have been resolved with the 0.9 release of Zeppelin and installation of the interpreter is again simple and straightforward.
Earlier today Joel and I discussed offline about trying to get this content merged for the 8.8 Guide release and with these issues fixed we agreed it's time to try to get it done. I'll push up a new branch doing just that for review before merging.

> Visualization is now a fundamental element of Solr Streaming Expressions and Math Expressions. This ticket will create a visual guide to Solr Math Expressions and Solr Streaming Expressions that includes *Apache Zeppelin* visualization examples.
> It will also cover using the JDBC expression to *analyze* and *visualize* results from any JDBC compliant data source.
> Intro from the guide:
> {code:java}
> Streaming Expressions exposes the capabilities of Solr Cloud as composable functions. These functions provide a system for searching, transforming, analyzing and visualizing data stored in Solr Cloud collections.
> At a high level there are four main capabilities that will be explored in the documentation:
> * Searching, sampling and aggregating results from Solr.
> * Transforming result sets after they are retrieved from Solr.
> * Analyzing and modeling result sets using probability and statistics and machine learning libraries.
> * Visualizing result sets, aggregations and statistical models of the data.
> {code}
>
> A few sample visualizations are attached to the ticket.
