Subject [jira] [Created] (SOLR-10504) Add echo Streaming Expression
Date Tue, 18 Apr 2017 02:25:41 GMT
Joel Bernstein created SOLR-10504:

             Summary: Add echo Streaming Expression
                 Key: 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:

select(echo("hello world"), analyze(echo, analyzerField) as out)
