Does the Tridion Search Indexing Service push items into Solr immediately?
I'm asking because our client has noticed that item they know are there are not appearing in search results. When I checked, I could see these components where only created 2 or 3 days ago but did not appear to be in the search index.
I checked the QUEUE_MESSAGES table and can see an a couple of entries for each new item, one with ACTION_ID 1 and and one with ACTION_ID 2.
I'm running the re-index tool but I'm not sure why none of these items made it into the index. Is there away to see how "old" the Solr index is, so the last time it was updated?
Re-indexing and restarting the indexer service appeared to resolve this issue. The QUEUE_MESSAGES table now appears to clear of any for the search queue so I my set-up if I see the number of items in this table growing I treat that as an alert to maybe perform another re-index/indexer restart.
