Hi,
It appears this was broken in 8.0 by
https://issues.apache.org/jira/browse/SOLR-12768
And then fixed in 9.0 (not released) by SOLR-15156
I didn't back-port the fix because I thought users might be relying on the
escaping behavior. I didn't realize such escaping didn't exist before
SOLR-12768. In light of this, the change would make an appropriate
addition to 8.9 but not a bug-fix version.
A work-around is to express your query without colons, since the internal
logic is gated on that. So something like:
childFilter='+{!field f=docType v=child_doc_type} +{!field f=color
v=Red}' etc. Disclaimer: I didn't test that; it *may* be necessary
to move out some of this into other parameters based on parsing
rules/restrictions e.g. childFilter=$theChildFilter and then add a
top-level param. But I think it's not needed.
