Search documents based on '_version'

Looking for querying on documents using '_version' field.
Out of my 20M records in Elastic Search and few records missed the latest updates.
I realized those records have '_version' value as 1,

Can some help me to query to find the list of records.?
I tried below query

"
query:
filtered:
filter:
_version:
lte: 1
