Search backend for Django App on Heroku

Question

On my development app I'm using a combo of Haystack for search with Whoosh as the backend.

However, when I deploy to Heroku my search is no longer working, even after running python manage.py update_index.

Upon some research, I discovered that it's because of Heroku's read-only file system.

Is there any free solution to get around this on Heroku so that I can get search working? The addons I have looked at are ~$20/month and I'd prefer to get started with a free solution if possible.

It's not really practical to do this without a separate search server. Storage on Heroku's dynos are not read-only but they are ephemeral and individual to a dyno, and any production application will have at least two dynos. You might be able to set something up to run on a dyno but it's certain to be complex and fragile, whereas a third party service is turnkey. Most third party search add-ons scale with usage and many are free at the cheapest level, and if none of them fit the bill then you can always use non-Heroku search services, of which there are many.

Thanks Andrew. Is there a particular one that is free that you would recommend? – user1328021 Mar 28 '13 at 18:58
Not yet, but I will have to do this dance for my own project in a few months and will test a variety of services at that time. – Andrew Gorcester Mar 28 '13 at 20:26

Note that the dyno filesystem is writeable. Can you post the error you are getting?

You might want to take another look at Heroku add-ons. There are several Elastic Search add-ons that are in free beta or have free plans. Haystack supports Elastic Search:

I'm not getting any error-- rather the problem is that it's just not indexing my search at all. I run `python manage.py update_index` yet when I search for an object, it does not show up. On my local machine this issue doesn't occur. – user1328021 Feb 28 '13 at 18:53
