You’re gonna use Facebook.dll u can download it using Package Manager in Visual studio if u are using C# for example

NuGet Package here..

and code may look like this

public List<string> Facebook(string query)
    {
       // Facebook.FacebookAPI api = new FacebookAPI();

        List<string> list = new List<string>();
        string[] arr = new string[5];
        string result = null;
        FacebookAPI api = new FacebookAPI(token);

// query is ur search criteria

        JSONObject q = api.Get("https://graph.facebook.com/search?q="+query+"&type=post");
        foreach (JSONObject item in q.Dictionary["data"].Array)
        {
            if (item.IsDictionary)
            {
                foreach (KeyValuePair<String,JSONObject> jso in item.Dictionary)
                {
                    if (jso.Key == "message"/* || jso.Key == "name" || jso.Key == "description" || jso.Key == "link"*/)
                    {
                        for (int i = 0; i < 5; i++)
                        {
                            arr[i] = jso.Value.String;

                        }
                        list.Add (jso.Value.String);

                    }
                    else if (jso.Key == "likes")
                    {
                        foreach (JSONObject like in jso.Value.Dictionary["data"].Array)
                        {
                            foreach (KeyValuePair<String, JSONObject> lik in like.Dictionary)
                            {
                                if (lik.Key == "name")
                                {
                                    result += lik.Value.String;

                                }
                                else if (lik.Key == "id")
                                {
                                    result += lik.Value.String;    
                                }
                            }
                        }
                        foreach (KeyValuePair<String, JSONObject> count in jso.Value.Dictionary)
                        {
                            if (count.Key == "count")
                            {
                                result += count.Value.String;
                            }
                        }
                    }
                    else if (jso.Key == "from")
                    {
                        foreach (KeyValuePair<String, JSONObject> froms in jso.Value.Dictionary)
                        {
                            if (froms.Key == "name")
                            {
                                result += froms.Value.String;
                            }
                        }
                    } 
                }
            }
            /*
            else if (item.IsArray)
            {
                foreach (JSONObject j in item.Dictionary["data"].Array)
                {
                    if (j.IsDictionary)
                    {
                        foreach (KeyValuePair<String,JSONObject> x in j.Dictionary)
                        {
                            result += (x.Key + " --- "+x.Value.String);
                        }
                    }
                }
            }
             */ 
        }
        return list;
    }

you can of course change post and query to whatever you want to search in Facebook Graph API

and there is another way to do that using FQL and its really easy

hope that will be helpful.
