Reading Exam Ref 70-332: Advanced Solutions of Microsoft SharePoint Server 2013, I made the following finding:
Enabling continuous crawling means that search results can appear before a crawl is completed because adding a document starts a new crawl that might finish before the first crawl. A user can add a document and have it appear in the search results within seconds of it being added, which can greatly improve the end-user experience and help users find the most current information as soon as possible.
However, it doesn’t say what happens when multiple documents are uploaded at the same time in a “bulk upload”, which has a default maximum of 100 documents. I don’t want 100 simultaneous crawls running in parallel when multiple documents are uploaded. Nevertheless, I’m not sure this doesn’t happen.
Does Continuous crawl start a new crawl on each uploaded document while uploading multiple documents at the same time?
