Bug description

Searching for "@" or strings containing "@" doesn't work or it doesn't show the matched messages.

Steps to reproduce

• send or receive messages containing "@"
• go to the chat list
• (A) search for "@"
• (B) search for a string containing "@"

Actual result: (A) it says that no messages are found. (B) matching results don't include "@" character in the preview.

Expected result: the search engine should find any message containing "@".

Also fails to match . so email addresses such as example.email@server.com have to be searched like exampleemailservercom. Punctuation seems to be filtered out here.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.

The problem is solved by removing the "@" sign from the CharacterSet.punctuationCharacters set defined in the static function charactersToRemove in the FullTextSearchFinder.swift file. So, adding charactersToFilter.remove(charactersIn: "@") after line 101 seems to resolve the error in the search part.

But the main issue here is this; There are many characters that can be used in search in Apple's punctutationCharacters. I haven't tested all of them, but it is necessary to compare them with Android and determine which ones will be included.

Thanx.

The search also fails to find "€".
