Search for Tweets
Syntax
Description
d = search(c,tweetquery)tweetquery.
d = search(c,tweetquery,parameters)
d = search(c,tweetquery,QueryName1,QueryValue1,...,QueryNameN,QueryValueN)
Examples
Use a Twitter connection object to search for Tweets.
Create a Twitter connection using your credentials. (The values in this example do not represent real Twitter credentials.)
consumerkey = 'abcdefghijklmnop123456789'; consumersecret = 'qrstuvwxyz123456789'; accesstoken = '123456789abcdefghijklmnop'; accesstokensecret = '123456789qrstuvwxyz'; c = twitter(consumerkey,consumersecret,accesstoken,accesstokensecret);
Check the Twitter connection. If the StatusCode property has the value
            OK, the connection is successful.
c.StatusCode
ans = 
    OKSearch for Tweets using the Twitter connection object and the search term MathWorks.
tweetquery = 'MathWorks';
d = search(c,tweetquery)d = 
  ResponseMessage with properties:
    StatusLine: 'HTTP/1.1 200 OK'
    StatusCode: OK
        Header: [1×25 matlab.net.http.HeaderField]
          Body: [1×1 matlab.net.http.MessageBody]
     Completed: 0
d is a matlab.net.http.ResponseMessage object. The
          StatusCode property shows OK, indicating a
        successful HTTP request.

        retrieve other Twitter data, use the getdata
        function.
Use a Twitter connection object to search for 20 Tweets. Specify the number of Tweets to retrieve as a structure.

...The field text in each structure contains the text of
                        one Tweet.
(These values do not represent real Twitter data.)
You can search for other Tweets using the search
                        function. To retrieve other Twitter data, use the getdata function.
Input Arguments
Twitter connection, specified as a twitter
            object.
Tweet search term, specified as a character vector or string scalar.
Example: "MathWorks"
Data Types: char | string
Web service query parameters, specified as a structure. Each parameter is specified as a field in the structure. Set the field to a specific value in the structure. For example, specify the number of Tweets to retrieve:
parameters.count = 20;
The Twitter REST API defines web service query parameters that it accepts as part of an HTTP request.
Data Types: struct
Web service query parameters, specified as one or more pairs of name-value
                        arguments. A QueryName argument is a character vector or
                        string scalar that specifies the name of a query parameter. A
                            QueryValue argument is a character vector or string
                        scalar that specifies the value of the query parameter.
The Twitter REST API defines web service query parameters that it accepts as part of an HTTP request.
Example: 'count',20 retrieves 20 Tweets.
Data Types: char | string
Output Arguments
Twitter data, returned as a matlab.net.http.ResponseMessage object.
To retrieve Twitter data, access properties in d, for example:
data = d.Body.Data
data = 
    
      struct with fields:
    
               statuses: {50×1 cell}
        search_metadata: [1×1 struct]
Continue to access the nested structure data to retrieve Twitter data. For accessing nested structures, see Access Data in Nested Structures.
Limitations
- The Twitter REST API - GET search/tweetsendpoint specifies that you can retrieve up to a maximum of 100 Tweets at a time.
- The Twitter REST API - GET search/tweetsendpoint specifies that you can retrieve up to 7 days of historical Tweets.
