Documents are not synced into couchbaselite from Couchbase Database


I created Sample document in couchbase Database. I tried to pull the documents from Main Couchbase DB to local couchbaselite. Here manually created document is not synching into couchbaselite Database.
how I get manually created document into local Couchbaselite?
Is there any way to find the documents information from sync gateway function calls?
Why newly created document is not loaded into local couchbaselite DB?
