We've replaced the built-in confluence search with a Google Search Appliance that we've customized to produce better (for us) search results and we've been using Confluence that way for a couple years now.
Since we're not using the built-in search to search for any type of content, would it make sense to completely disable the indexing tasks to save system resources? Or are there other features (such as macro autocomplete) that rely on the indexes to function properly?
