I recently came across a scenario where I wanted to reindex a specific item(s)/folder instead of the full content tree.
Typically I would have reindexed from Indexing Manager in Control Panel which takes a good amount of time to rebuild all items.
Instead, I chose the item(s)/folder, navigated to the Developer tab, and clicked Re-Index Tree. It was done in less than a minute!
This will rebuild the Item(s) to all the indexes in your solution and I feel this is very quick as compared to traditional re-index.
Note: If you don’t see Developer tab in the menu, you need to enable it by right-clicking on the menu and select the developer option.
Note: Same trick works with Web DB when you switch it in Sitecore Desktop.
Hope this helps someone. Any questions, leave a comment.
Happy Sitecoring.
