Param Substitution in Stream Expressions?
My application relies on local parameter substitution pretty heavily due to
escaping issues and being able to re-use clauses.
Is there any way to use param substitution in a /stream expression?
(This doesn't work):
POST /stream {
'expr': 'search(collection1,q=$test,fl="doc_id",sort="doc_id
asc",qt="/export")', 'test': 'contains:blah'
}
Cheers,
JAG

Hi,
You'll need to set a Java system property at startup to run macro expansion
in Streaming Expressions.
See the commit below which references the jira with the security concerns:
https://github.com/apache/solr/commit/9edc557f4526ffbbf35daea06972eb2c595e692b
The parameter setting is as follows:
-DStreamingExpressionMacros=true
