Problem: It's hard to search in a specific conversation thread. This translates as multiple problems:
Hard to search inside a conversation thread (Ctrl+f or cmd+f are not searching through the collapsed message. Also, on the browser "cmd/ctrl+f" searches in the entire page and not just in P3).
Workaround: Scrolling the entire thread and opening all the messages before doing a ctrl+f search
Search results are ranked chronologically by the date of the last message and not the one that matched the search (see this portal idea)
Front returns conversation where the search keywords can be in different messages in a conversation thread (see this portal idea)
