Sharepoint Search crawl success without new data

Hello all,

I got an issuse about search crawl:

Issue:

          When i update data (Ex: A->B) then i start crawl data but data still got A value.

Solution:

          I Index Reset in search service application and configure scope again then i crawl full data => i got new result (B value). If you meet problem about people search without item, remember check sps3://yourwebapp:port in content source

Thanks all.
