@bingeng99 you're totally right. adding the reference doc:
https://oss.redislabs.com/redisearch/Commands.html#ftsearch
Also, I think we should take the query_test.go test file and add a test case specifically named 'TestQuery_serialize'. Will submit a PR that will add testing for the serialize method. Afterward, when that testing addition PR is merged, I think you should expand that same test with the Language addition ( so that codecov test passes). What do you think?

[bingeng99]

@filipecosta90 I have added test cases for query serialize method.
