How can I get the desired output at query time for my edge-ngram autocomplete, given my mappings?

Desired Output

"Fish Lake, New Zealand"
"Fife Rock, New Zealand"
"Fish Rock, New Zealand"
>"Finger Rocks, New Zealand"<
>"Lake Fiddle, New Zealand"<

Actual Output

"Fish Lake, New Zealand"
"Fife Rock, New Zealand"
"Fish Rock, New Zealand"
>"Lake Fiddle, New Zealand"<
>"Finger Rocks, New Zealand"<

Maybe Prefix Query resolve it but for solutions autocomplete Completion suggester and the search_as_you_type are best solutions.
