Is kafka a good option for feed a web app?

We are proposing an arch to use kafka as a layer to comunicate microservices with our web application.

But I realize that we cannot query or filter the data what comes from a Kafka topic, lets say for example that we have topic which manage the students in our app and we have a dashboard which show us blocks of ten students I don not see a way to ask kafka for the newest 10 students, Kafka will give me all the students so far, so if I have 1000000000 students my app should order and filter those, am I right ?
