User has been deleted from UPS, however its getting display in People Search in search site - why ?

Hello,

I have deleted user into UPS, however its still being display in people search.

I believe search crawl will delete the information from people search - However I am not sure whether its correct approach to run delete information from people search.

If user is not available in UPS then why user's information is being display in site ? and by when it may delete automatically?

Thanks and Regards,
