I have a some question!
Previously I used Elastic 2.3 Version and now upgrade to ES 5.1
In 2.3, Analyzed or Not analyzed type is String.
but from 5.0, I noticed that the type was changed to text and keword.
I was test the index by migration tool.
but result is does not need to reindex the old index.
Is it normal to use without changing the type?
this is my system information.
- OS : centos7 operating system.
- upgraded ES from version 2.3 to version 5.1
- Using the Java API.
