| The Streaming Expression library includes a powerful |
| mathematical programing syntax with many of the features of a |
| functional programming language. The syntax includes variables, |
| data structures and a growing set of mathematical functions. |
| |
| This user guide provides an overview of the different areas of |
| mathematical coverage starting with basic scalar math and |
| ending with machine learning. Along the way the guide covers variables |
| and data structures and techniques for combining Solr's |
| powerful streams with mathematical functions to make every |
| record in your Solr Cloud cluster computable. |
