Changing a Crawl Rule, must I do a full crawl to update the change

Question

I made a crawl rule change that should impact a document library and cause some new documents to be inserted. However since it's a smallish change, and a full crawl can take awhile on our site (half a day most likely) I'm hoping I can update the library only with those changes somehow. Forcing a reindex in advanced settings then doing an incremental did not index the documents. Am I stuck doing a full crawl or is there another way to get those documents in?

Answer 1

When Crawl Rules have been added, deleted, or modified, a full crawl is required.
