Hi Dominique,
Sorry, I was in a hurry to create a simple enough yet similar case that we
face with internally.
reporting_to indeed is the right field , but the same error still persists,
something is seemingly wrong when invoking the *subquery *with *fromIndex*
{
params: {
q: "*",
fq: "*",
rows: 5,
fl:"*,subordinate:[subquery fromIndex=Collection2]",
subordinate.fl:"*",
subordinate.q:"{!field f=reporting_to v=$row.id}",
subordinate.fq:"*",
subordinate.rows:"5",
}
}
{
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","org.apache.solr.common.SolrException"],
"msg":"while invoking subordinate:[subqueryfromIndex=Collection2] on
doc=SolrDocument{id=stored,indexed,tokenized,omitNorms,indexOptions=DOCS<id:1>,
first_name=[stored,index",
"code":400}}
Any help much appreciated, hopefully it's an error with the syntax I've
been using.
Regards,
Norbert
