text searching seems to have some differences between server and cloud

specifically this proximity search 

text ~ "\"like a\"~0"

on the server returns an exact match where 'like' and 'a' are adjacent

on the cloud this returns items with text between the words.

Is this a known issue.

is this a known feature or bug?

To recreate run the above JQL search on words known to be adjacent and separate in different issues using server and cloud instances
