• search_api_solr shows "Outdated solr configuration" #15.

How This PR Solves The Issue

Adds documentation on how to fix outdated Solr config files message.

Also updates the "Alternate Core Name" section, the first step (1. Remove the #ddev-generated at the top of the file.) isn't necessary, it seems?

Release/Deployment Notes

It all looks great, just the one question about why you removed #ddev-generated notice.

[rfay]

If you don't remove the #ddev-generated then the file will be recreated with the default file on ddev restart.

[gitressa]

I removed it because after creating the file .ddev/docker-compose.solr-env.yaml, adding this:

services:
  solr:
    environment:
    - SOLR_CORENAME=somecorename

and restarting DDEV, at no point do I see a line saying #ddev-generated, so I removed that first line ...

Or is that first line about something else?

[gitressa]

Great, thanks!

[rfay]

Thanks for the contribution and for keeping your eye on this repo. You know and use solr far more than I do, and it needs knowledgable folks following it.

You're welcome, I am glad I could help. It's a privilege to assist you with DDEV, it's an amazing web developer tool.
