[jira] [Commented] (SOLR-12505) Streaming expressions - fetch()
does not work as expected
[ https://issues.apache.org/jira/browse/SOLR-12505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17429017#comment-17429017 ]
David Eric Pugh commented on SOLR-12505:
----------------------------------------
I just ran into similar problems. In the setup I am using ([https://github.com/querqy/chorus/blob/master/solr/configsets/ecommerce/conf/solrconfig.xml#L86)] the /select handler uses defType=edismax.
I'm going to change up my setup to remove the defType=edismax on the raw /select.
Having said that, would it make sense for the fetch() to instead hit the realtime GET endpoint instead? Since we aren't really running a search.....

> Key: SOLR-12505
> URL: https://issues.apache.org/jira/browse/SOLR-12505
> Project: Solr
> Issue Type: Bug
> Components: streaming expressions
> Affects Versions: 7.3.1
> Environment: Windows 10, Java 10, Solr Cloud 7.3.1
> Reporter: Dariusz Wojtas
> Assignee: Joel Bernstein
> Priority: Major
> Attachments: names.zip

> The issue:
> # when I try to use fetch() within a streaming expression, it does not enrich the inner source data. The result is exactly the same as if there was no surrounding fetch() function.
> # but it works if I try to do a leftOuterJoin() function instead.
> Use the attached 'names' collection configuration.
> SOLR works in _cloud_ mode, streaming expressions do work, ie. stream(), join(), etc
