Be able to search a specific property in inbox (Smart search inbox)

AIrbnb has filters on inbox but its quite clunky. A simple option to be able to search:

House 4 and then all conversations show up in date order would be great.

To add on to this being able to add a name/ phrase after to further narrow the search would be great.

House 4 Sophia

House 4 Travel cot

House 4 James Travel cot

I don't think filters are needed for inbox if the search function is intelligent
