hi,Brant.Thank you for your answer.

According to your prompt, I need to recreate the index.But I have 2000 users in use here.

If I perform index recreation, will it affect the index and use of my other users?

Are there any other risks?

I look forward to your reply. Thank you.

Brant Schroeder

Content indexes are built on the server to ensure quick response when using the application. The indexes are built from the database data. I would suggest rebuilding outside of work hours as it may cause application slowness.

Jay dong

Thank you very much for your reply.

In addition to slowing down the server, it will also affect my previous save De.

I am very worried because the creation of this index will affect the relationship between my other data, so I hesitate to move.

Welcome!
