I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
I am using the latest version of Open WebUI.

I have read and followed all instructions in README.md.
I am using the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have included the Docker container logs.
I have provided every relevant configuration, setting, and environment variable used in my setup.
I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
Start with the initial platform/version/OS and dependencies used,
Specify exact install/launch/configure commands,
List URLs visited, user input (incl. example values/emails/passwords if needed),
Describe all options and toggles enabled or changed,
Include any files or environmental changes,
Identify the expected and actual result at each stage,
Ensure any reasonably skilled user can follow and hit the same issue.
When the administrator queries user chat history in the backend or searches for a specific keyword in the frontend, the entire system crashes, preventing other users from accessing the system normally. I checked the system load, and there is still significant redundancy. I hope performance can be optimized so that performing these operations does not affect other users' normal use.
Actual Behavior
整个系统卡死
Steps to Reproduce
在管理员后台查询用户聊天记录或在前台搜索某一个关键词的时候
Logs & Screenshots
No error

在管理员后台查询用户聊天记录或在前台搜索某一个关键词的时候，会导致整个系统卡死，其他用户也无法正常访问。我查看了系统负载，还有很大冗余。希望可以优化性能，在执行这类操作的时候不要影响其他用户正常使用。
