Need to push javascript objects ( not from collections ) asynchronously for a specific user from server to client on meteor

Any user (client) making a research on my meteor app would call a meteor
method that will send asynchronously results to this client when it
founds something ( could be by searching many different external apis
for exemple ) and possibly would inject it in a client-side only (none
persistent) collection. how ?

Does this help (your use case is different, but hopefully you’ll get the idea)?
