The sync info CI is not happy. Not sure if there's something wrong with GITHUB_TOKEN or I missed something.

It looks like your changes make sense. When AnswerAmount is 0, the query should actually be all of them. When it's not 0 it should be the query condition. let us ask @kumfo to confirm this.

You should not change this code, when search conditions has answers:0, the search results should not include questions that have existing answers.

When cond.AnswerAmount is -1, the search result no limit. Could you please check this code?

Please refer to my comments.
