Reindex would require the application to get the full new document. Since
in my case the changes are incremental (like delete a field or add a
field), I will have to re-read the full contents to reindex.
I found following update operation which can remove a field from the
document. It uses script to do this. My questions is can this be done
without script using pure Java API. The reason I am trying to avoid script
is because it is disabled by default.
We can also remove a field from the document:
curl -XPOST 'localhost:9200/test/type1/1/_update' -d '{
"script" : "ctx._source.remove(\"text\")"
}'
