There is a way to recrawl on demand only one document?

I seen i can refresh, reescan or rebuild a Source, Refresh is the most similiar that I want but I want to make sure what is the best way.

The most picky method to only index one document would be to work with a `push` source.

This said, the answer to your question depends on the type of source you are crawling. For the bigger picture, this article explains the differences between a refresh, a rescan, and a rebuild.

Re-Indexes everything.

Re-indexes only items found to have changed. Although this may seem better than a rebuild, all the items of the external system are scanned. So, this is not much more efficient.

Items that have changed according to the external system. If only one of your items has changed, this is the way to go, but it is important to mention that not all sources support being `refreshed`.
