Completion Suggester - First element of input array gives suggestion well but not the later

Elastic Stack Elasticsearch
1

For completion suggestion, I have input as follow:

"input": ["com.google.playstore", "New Playstore"]

Let say for query com.google or 'com.goo' or comgoogl, above works well. But when searching for New Playstore or new, suggestion is not displayed.

If input is reversed, the later New Playstore or new works well but not the com.google or 'com.goo' or comgoogl.

"input": [ "New Playstore", "com.google.playstore"]

Wondering what could be its reason? Thanks in advance.
