BUG: Using --url when running index on a multisite not working. Getting full network index always.

[colegeissinger]

I looked everywhere and didn't see any mention about the index command no longer supporting the global WP-CLI command --url so reaching out here to see what's up? This may not be a bug but it was unexpected for me.

I'm working on upgrading to v4 of ElasticPress on a couple of large multisite networks. Historically I could control the indexing to a single site when needed, but after upgrading to versions 4.0.0+ the CLI command wants to index the full network no matter what.

While normally I want a full network index, I have found in one particular network there is a large sum of content to index across 60+ sites. When running the full index it eventually errors out once it reaches the end of the index with Error: Network alias creation failed for posts ..., and I was trying to debug further by syncing a single site but found the index command doesn't seem to honor the --url parameter anymore after 4.0.0. This still works fine in 3.6.6 though?

Steps to Reproduce

1. In your command prompt, run the index CLI command for a single site in your subdirectory multisite install wp elasticpress index --setup --yes --url=https://test-multisite.test/some-sub-site
2. Observe that the indexing logs report starting from site ID 1 and continue through all the sites in the network.

Expected behavior
I expect the index command to ONLY focus on indexing the site provided in the --url parameter offered by WP-CLI which was supported in ElasticPress 3.6.6.
