-------------------------------------
Summary: Add echo Streaming Expression
Key: SOLR-10504
URL: https://issues.apache.org/jira/browse/SOLR-10504
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
The *echo* Streaming Expression takes a text string as an argument and emits a
single tuple that "echos" the text string.
This will allow constructs that "echo" text to various decorators such as
*select*, *cartesianProduct* and *classify*.
Sample syntax:
{code}
select(echo("hello world"), analyze(echo, analyzerField) as out)
{code}
