The Heroku Logplex only stores the last 1500 log lines from your application dynos and add-ons. To store and search logs long-term, you'll need to stream your logs to an external service provider. Heroku provide many logging add-ons: https://elements.heroku.com/addons, or you can use your own service by setting up a log drain: https://devcenter.heroku.com/articles/log-drains.
