PostgresIndexQueryBuilder - shall we use to_tsquery vs. plainto_tsquery ?

[missedone]

hi, folks

we're using Postgres index (rather than ES index) in our QA env, and we noticed some issues when searching the workflows.
after digging into the source code of
https://github.com/conductor-oss/conductor/blob/main/postgres-persistence/src/main/java/com/netflix/conductor/postgres/util/PostgresIndexQueryBuilder.java#L83-L88

        public String getQueryFragment() {
            if (operator.equals("IN")) {
                return attribute + " = ANY(?)";
            } else if (operator.equals("@@")) {
                return attribute + " @@ to_tsquery(?)";

to_tsquery could be the issue
per the article http://blog.mochimarks.com/2017/03/should-i-use-plaintotsquery-or-totsquery.html
I'm thinking shall we use plainto_tsquery here vs. to_tsquery?
