Search Function Not Displaying Messages with Attached Images

Description:

Hello, I noticed a potential bug within the RocketChat platform, where messages, while having a certain keyword, are not being shown in the search results if there is an image attached. This behavior is observed both on the RocketChat Server v6.4.6, v6.5.0 the RocketChat Electron Client v3.9.9, and also when accessed through a web browser.

Steps to reproduce:

1. Go into any group chat on RocketChat.
2. Post a message with a particular keyword and attach an image to the message.
3. Use the search bar to look for that particular keyword.
4. Notice that the message with the attached image does not appear in the search results, even though it contains the searched keyword.

Expected behavior:

The message with the keyword and the attached image should appear in the search results.

Actual behavior:

Messages with attached images are not showing up in the keyword search results.

Server Setup Information:

• Version of Rocket.Chat Server: 6.4.6, 6.5.0
• Operating System: Linux
• Deployment Method: docker

Client Setup Information

• Desktop App or Browser Version: RocketChat.Electron: 3.9.9, Google Chrome: 119
• Operating System: Windows 10

Additional context

This issue is causing difficulties finding important messages embedded with images. Any help regarding this discrepancy would be deeply appreciated.

Screenshots

No source files, tests, or entry points are mentioned. Reproduce the search with a keyword-bearing message that has an attached image, then trace the search handling for messages and attachments; the issue is done when such messages appear in keyword results across the reported client paths.
