Examples
Locating a Sent Message Using Search Keywords and Deleting it
To delete a message that was sent, we can locate the sent message and delete it. The same can be done for multiple messages, at once. This example demonstrates how we can use the Search Snap to achieve this result.
This Pipeline uses a set of Pipeline Parameters as depicted in the following image.
We use the Send Message Snap to send a message defined as an expression to a Private Channel.
| Send Message Snap | Output |

Search Snap supports a variety of search keywords, besides exact words, like wildcard search (using *, #, and so on), sender, or recipient of the messages and files. We use this feature to perform two different search operations and combine their results to see if our message is retrieved.
So, after sending the message we use the Copy Snap to duplicate the output from Send Message Snap and initiate two Search operations - one based on the wildcard search and another on the sender's name/ID.
| Search by wildcard text | Output |
|---|---|
|
|
| Search by Sender | Output |
 |
|
We combine these search results using a Join Snap to ensure the results contain the message we want to delete.
| Join Snap | Output |
|---|---|

Now, we connect a Mapper Snap to transform the contain search results data to contain only the Channel ID and the timestamps of the messages. This will enable us filter the results and identify the latest message that we want to delete.

Connect a Delete Message Snap to the Mapper and pass the Channel and Timestamp values to it, to delete the message. The Snap deletes the message and shows the following output.
