Search (SOLR search)

Here are some notes about updating search results when SOLR isn't doing it automatically (which seems to be "always" as of this writing, Aug 2020). 

Force SOLR to index things in the queue

Webpage updates and new pages are supposed to be added to a queue, which is supposed to get worked on each time Cron runs. This stopped happening sometime in early 2020 or so. We can force the server to process the queue as follows:

Light touch (recommended)

1. Go to Configuration » Search » Search API » Default node index (also available via the Search Index link in the Admin » Shortcuts menu)
    
2. Click the Index now box, in the top line on the "Index now" section of the page. This will force the search service to index anything still in queue.

Next level

This option re-indexes the site, but it doesn't destroy the current index, so it's a little less heavy-handed than the third option, below.

It does force the server to do a lot of indexing work. This is best done in a slack time like overnight. 

1. Go to Configuration » Search » Search API » Default node index (also available via the Search Index link in the Admin » Shortcuts menu)
    
2. Click the GRAY Queue all items for reindexing box at the bottom of that page. This will force the server to re-index the whole site but won't destroy the current index.  
    
3. Click the Index now box, in the top line on the "Index now" section of the page. This will force the search service to update the index to include everything on the site.

Heavy hand 

Best done overnight because the search will be nonfunctional or barely functional for [hours?].

1. Go to Configuration » Search » Search API » Default node index (also available via the Search Index link in the Admin » Shortcuts menu)
    
2. Click the RED Clear all indexed data box at the bottom of that page. This will force the server to re-index the whole site.
    
3. Click the Index now box, in the top line on the "Index now" section of the page. This will force the search service to index everything.
