You’ve posted in API so assume you are providing feedback about the API?
This isn’t a particularly helpful bug report.
You need to share logs, go into much more technical detail about the calls and responses.
Note that the API cannot use web search you need to implement that for yourself.
Then, even if you have implemented web search yourself, you would need to make sure the target pages were high ranking enough to be returned and not blocked by a sign in. Are the FB pages public, for example?
Can you tell us more about your web search function? What was the query and what was the data returned?
