Small doc update, so that users of the documentation can easier understand what are database indexes.
Issue link https://code.djangoproject.com/ticket/21986
I'm not too familiar with django, so there could be a better link that wiki.
To test out my change, perform following steps:
Cavet: This is my first pull request, let me know if I've missed something.
Added wiki link for database indexes on topics/db/optimization.html
Potential fix for https://code.djangoproject.com/ticket/21986
Merge branch 'master' of github.com:django/django into issue21986
The Wikipedia article for database indexing is a little dense on technical details. While a valuable resource for those looking for more detail, a passing hint that you should index fields you do lookups against often would serve most people reading this page as good as is Priam probably necessary.
Agreed, please send a new PR if you can expand this a bit as noted above and on the ticket, thanks!
