------------------------------------------
Summary: known field's empty value can vanish via
add-unknown-fields-to-the-schema updateRequestProcessorChain
Key: SOLR-11855
URL: https://issues.apache.org/jira/browse/SOLR-11855
Project: Solr
Issue Type: Bug
Environment: *known field's empty value can vanish via
add-unknown-fields-to-the-schema updateRequestProcessorChain*
This appears to be due to the "remove-blank" processor in the
"add-unknown-fields-to-the-schema" process chain i.e. remove-blank applies to
known as well as unknown fields (and when field guessing is disabled then
remove-blank logic also stops).
Technically there's nothing broken here but I'm wondering if remove-blank might
be removed (no pun intended) from the _default configuration or if the
{code}
WARNING: Using _default configset. Data driven schema functionality is enabled
by default, which is NOT RECOMMENDED for production use.
To turn it off:
curl http://localhost:8983/solr/collectionA/config -d '{"set-user-property":
{"update.autoCreateFields":"false"}}'
{code}
wording might be revised somehow to better account for the remove-blank
functionality?
