Description

In English, words are segmented by spaces, but in other languages such as Chinese and Japanese, they don't use spaces or other separators to segment words in a sentence. It seems Telegram can only search the entire word surrounded by some separators, it's very inconvenient and even unusable for Chinese and Japanese users.

Expected Behavior

When search "今天" for "今天天气真好"，Telegram will show "今天天气真好".

Actual Behavior

When search "今天" for "今天天气真好"，Telegram will show "No Result".

Steps to Reproduce

1. Send "今天天气真好" to saved messages
2. Search "今天" in saved messages
3. The result is: "No Result"

Environment

Device: iPhone 14 Pro

iOS version: 16

App version: 9.4.3
