I have read lots of articles and Blog about continuous crawl, and I need more details about the Continuous crawl interval settings. I am aware that the default is 15 min and min can be set to 1 min according to MS article Also, I am aware that more than more crawl can be run in parallel. Now, If I changed an item in SharePoint, does that mean it will start a new crawl? or is it based on the interval settings?
Here is an example. let us say I have a content source that takes 2 hours to crawl, and there is a current crawl still crawling the content. If I added/modified an item(s) would that start an new crawl or a new crawl will start based on the interval settings?
The reason I am asking this question is to be able to estimate how soon newly/modified items become available in search results.
