Christine Poerschke updated SOLR-11852:
---------------------------------------
Attachment: SOLR-11852.patch
Attaching a rough proof-of-concept where a new StreamingExpressionWrapperModel
class extends the abstract WrapperModel class added by SOLR-11250 -- the
{{WrapperModel.fetchModelMap()}} implementation uses a streaming expression.
A shell script {{ltr-model-from-streaming-expression-poc.sh}} demonstrates how
a streaming expression can be used to retrieve a model stored as a document
field in a different collection.
