I have a use case where none of the document in my solr index is changing but
I still want to open a new searcher through the curl api.
On executing the below curl command
curl
"XXX.XX.XX.XXX:9744/solr/mycollection/update?openSearcher=true&commit=true"
it doesn't open a new searcher.
Below is what I get in logs

I don't want to do a complete reload of my collection.
Is there any parameter that can be used to forcefully open a new searcher
every time I do a commit with openSearcher=true.
In our collection there are few ExternalFileField type and changes in the
external file is not getting reflected on issuing commits (using the curl
command mentioned above).
Thanks in advance for the help
