It looks like those designing the Chat are not really using it. Searching the chat history is still an awful experience:
1. When you are in a conversation with a person and want to search for something, you want BY DEFAULT the results from the conversation with THAT person. But no, the smart designer of Chat was thinking to flood you first with a lot of results and then to ask you for few additional clicks to filter what you need...
Please change the default to show the results for the current conversation or add another quick find or provide an option to setup the default.
2. After you spend time filtering the results, someone had the "great idea" to limit the number of the results displayed. Really? So I know that the discussion is there but I'm not allowed to reach it other than scrolling manually few months back?
Please remove the limit of the number of the displayed results.
3. When you click on a found result, the conversation window it is showing only that sentence and the brilliant message: "Go to the channel to see the rest" :)))) And you click that only to discover that you need to scroll manually few months back :))))
Please jump directly to the day/hour of a found result and display the surrounding text.
4. It is not enough that you are limited regarding the number of the displayed results, but the Date range filter does not let you to select a custom time interval, for example: 1/1/2017 - 1/15/2017. You can select only "This year" and then it doesn't show you all the results :)))
5. Scrolling back through chat history it is terrible. You cannot jump easily to a previous week or month and you have to wait patiently until all the intermediary text is loading. Page Up stops working after a slower load of text and you need to click in window to make it work again.
Sorry for the angry tone, but I have a very hard time finding a lot of info I need. It is a pain to find fast and easy

Searching for something works (mostly), however if the thing you're search for is sufficiently far back in time, then it's nigh impossible to actually get results back. Clicking the message says "go to chat to see the rest", but clicking on that does nothing but take you back to the chat at the current time, rather than the target message. If you bookmark the message and try to get at the location in chat via that, then the client just lags and eventually crashes. (while chewing up 100% CPU) Tried the desktop client (developer preview), web client Chrome, web client Edge, all won't work for really big chats. It seems like it's trying to load the entirety of the chat conversation between now and the point in time that the message happened and then also trying to render and scroll up for that. This is crazy inefficient. It should load a few screens before that chat message, a few after, and then redraw. (so that total effort is nearly 0 rather than "10,000 lines of chats")

Search functionality:
1. Limit Search To:
* All of Microsoft Teams
* All Chats
* Only chats including [select input]
* All Teams
* Only Team(s) [select]
* All channels in a team
* Only channel(s) [select]

The search function is currently very poorly received across our area because it is just a massive search string.

I would like the ability to restrict a search by Team and/or Channel and/or Individual
In order to have a more targeted search result
So that I can more quickly and efficiently find the correct result.

Additionally - searching in User Feedback Forums is sub-optimal. It would be great to be able to sort by votes to see if there are already dozens (or hundreds or thousands) of votes for an idea. Right now I see hundreds of 'search options' results. And I'm pretty sure they're almost all duplicates.

Thanks!

In a big organization environment, we have a lot of chats, Teams channel going on. When trying to search certain thread/conversations, filter options built in Teams work fine for the most. But when trying to search certain dates to see the whole thread, it is kind of impossible, without having an option to select date range with calendar pop up to choose the date ranges. without this feature, I am having to go scroll up and down to find the exact date, time etc. Real pain....
So far with date range filter, it is set to certain period of time: Yesterday, this week, last week, month, year etc. I strongly believe having ability to select specific date range is a lot more helpful than current settings.

This used to be a feature, but now you've removed it?

If I want to find a conversation I had with someone 6 months ago, my only option is to scroll up, wait for messages to load, scroll up some more, wait some more and so on until I finally reach that part of the conversation timeline.

Search used to return messages that, when clicked on, took me to the place on the timeline where we had the discussion I'm looking for. Now clicking on the message only shows the message in isolation with no way of seeing it in context.

You took a useful, normal feature and stripped it away. I can't begin to fathom why.
