This sounds like a really interesting problem to work on. Are you hiring anyone for this team (esp those new to search)?
My experience as an experienced search developer is that there are very few search specific positions, if any, outside of the Bay Area. My current job is working remotely for a SF based company, where I do everything but search. :(
Awesome article! The article mentions the signals that the model found were most significant for a message. Curious to know if they're listed by order of significance in the article? And if not was wondering whether one or two signals were predominantly more significant than the rest.
Our top signals are age of the message, whether the message contains a link and whether the message is from the channel that you are currently viewing. We have several different models in production right now but those signals are generally the strongest.
Is there any possibility in the future users will be able to search ALL messages from a channel/private message, ever? It seems like Slack search cuts off after a certain point, and doesn't index into archived messages.
