Subject [jira] [Updated] (SOLR-10485) Add calc() Streaming Expression
Date Tue, 18 Apr 2017 19:25:41 GMT

     [ https://issues.apache.org/jira/browse/SOLR-10485?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joel Bernstein updated SOLR-10485:
----------------------------------
    Description: 
The calc() function can be used inside of the select function to execute Evaluators:

{code}
select(calc(), add(1, 1) as result)
{code}

The example above returns a single Tuple with the result of add(1, 1) in the *result* field.
This allows Streaming Expressions to perform calculations directly without requiring an underlying
stream.


  was:
The eval() function can be used inside of the select function to execute Evaluators:

{code}
select(eval(), add(1, 1) as result)
{code}

The example above returns a single Tuple with the result of add(1, 1) in the *result* field.
This allows Streaming Expressions to perform calculations directly without requiring an underlying
stream.
