Hey,

can you add more context to this question. What do you mean exactly? What is your assumption, **why** would expect this? And what does performance mean in this content?

Thx!

Hello,  
I am using search feature-Geo distance sort in Elasticsearch, in my case, I want to return the nearest driver to a specific car I want every time I do search query I will delete the current index and re-create it to make synchronization between MySQL DB and the index.  
My question is:- what is the best behavior delete-recreate the index or add/remove documents in the index in case I create an index in a server and the APIs actions that will affect the index in another server if I take the first scenario it will affect the performance of creating the index?

Thanks
