Re: Error when combining the collapse query parser with tagging and AND
Thanks for the suggestion, Mikhail!
So, from what I understand, this is expected behavior. Are there any
plans to make it possible for such a query combination to work in the
future?

Right; "tag" is one of several special local-params that may co-exist with
others. You needn't put another local-params wrapper just for "tag".
"cache" is the other that comes to mind.

Re: Error when combining the collapse query parser with tagging and AND
Posted by Markos Volikas <mv...@apache.org>.
Hi,
For anyone interested, we've been using the following workaround:
Instead of prepending the fq with the extra {!tag=foo} localParam, one
can directly add the tag=foo key-value pair inside the {!collapse}.
That is:
"q":"*:*",
"q.op":"AND",
"fq":"{!collapse field=id*tag=foo*}",
This works because tag registration in the constructor of QParser reads
this value explicitly
<https://github.com/apache/solr/blob/releases/solr/9.10.0/solr/core/src/java/org/apache/solr/search/QParser.java#L84>.
Best,
Markos

Hi,
For anyone interested, we've been using the following workaround:
Instead of prepending the fq with the extra {!tag=foo} localParam, one
can directly add the tag=foo key-value pair inside the {!collapse}.
That is:
"q":"*:*",
"q.op":"AND",
"fq":"{!collapse field=id*tag=foo*}",
This works because tag registration in the constructor of QParser reads
this value explicitly
<https://github.com/apache/solr/blob/releases/solr/9.10.0/solr/core/src/java/org/apache/solr/search/QParser.java#L84>.
Best,
Markos
