how can you search imessages on iphone by date

i'm trying to find messages from march of 2019 from a specific person and it's very important that i find these messages. The only way to prove something happened is is my messages and i know it's there i just don't know how to go back that far without sitting there forever scrolling to the top until I get back almost a year ago I tried searching things that we would've talked about around that time frame but it will only give me like a certain span to look at every so often it won't let me just keep going back it'll only break it down by the search of the wording please help I'm trying to help my mom with something Someone screwed my mom out of $5000 and I have the proof in my iMessages but I just can't figure out how to get back that far I've had every single iPhone since they were released so I should have practically every single message since the first one came out and I know that I have That entire time frame in my iMessages because when I search it'll take me either right before or right after it but as soon as the conversation doesn't match the wording I'm searching it doesn't show it in the feed so how do I just search backwards to a specific date and time
