Steps to Reproduce

This test is to check if our filtering performance is improved.

Import this file:
\\FILESERVER\potix\mkt\Keikai\Customer-sample\Chinese_hospital_vlookup

switch to sheet 4 column C
there's an existing filter, set "text filter" with criteria "contains: 8"

then the server is dead (zktest is temporarily out of service .... ). have to restart the server.
