Hi,
I want to test different similarities under ES. I have my big database A
and would like to export a sample of data in database B with a different
similarity. How can I do such a thing? The exporter tool here (
[https://github.com/mallocator/Elasticsearch-Exporter](https://github.com/mallocator/Elasticsearch-Exporter)) recreates the mapping
A into B but I cannot update after the export non-dynamic settings such as
the similarity. Any idea anyone?
Thank you,
Patrick

As I mentioned in your other thread, you cannot change the similarity of a
field dynamically. I would argue that we should be able to. If someone
wants to shoot themselves in the foot, they should be able to. 🙂
Sounds like your issue is how to transfer your data and use a new mapping.
I never used that plugin, but there seems to be an option to override the
mapping in the master branch. If not, some of the other export/import tools
might help. Never used anyone of them, so I cannot help much. Perhaps the
new snapshot functionality?

I solved my problem with exporter tool by exporting data first from DB A
into a file then importing from that file into DB B (that has its own
mappping).
Thanks again Ivan.
