* Disclosures and disclaimers# Guide to Facebook comments dataYou can fetch comments on a Facebook post or replies to a specific Facebook comment by using the `get()` method with the `facebook/posts/<id>/comments/preview` path. This document describes the parameters, and shows how to perform basic queries using the method.All of the examples in this document are taken from a Secure Research Environment use case and assume you have already created a Python or R Jupyter notebook and have created a client object. See Getting started to learn more.See Data dictionary for detailed information about the fields that are available.See Guide to bulk comments data for information about retrieving Facebook comments on multiple post or comment IDs using a single asynchronous query.**Estimating response size for comments**Estimating response size for any asynchronous search for comments (bulk or otherwise) has a limit of 1 million. A response size estimate of 1 million should therefore be interpreted as 1 million or more. See Search guide for more details on how to use asynchronous search, including estimating response size.## ParametersComma-separated list of fields you want included in the result. See Data dictionary for descriptions of all available fields.Sorting mode in which the comments are returned (only for synchronous endpoint). Available options:* `newest_to_oldest`: Comments are returned in reverse chronological order (newest first).* `oldest_to_newest`: Comments are returned in chronological order (oldest first).* `none`: No sorting is applied to the returned data.Default value: `newest_to_oldest`Boolean value that allows you to change the way of fetching comments. Available options:* `True`: All of the comments of the entity are returned, both nested and unnested. Since they are going to be returned in a “flattened way,” no sorting is applied.
