Index reset needed when adding Crawl Component + CrawlDB?

Question

I've added a second crawl component and a second CrawlDB to my Search Service Application in SP 2010. The topology is online where the second crawl component is attached to the new CrawlDB.

Do I need to make an index reset or any other configuration to make the new crawl active and working in parallel with first one?

Answer 1

You dont to reset the index if you just want new content coming to this component. But if you want to divide the content equally then Reset the Index and perform a Full Crawl.

Or if you see any issue after adding new crawl DB i.e crawling on content source not completed etc.then you need a index reset followed by full crawl.
