Base Query return 440 events, but stats result is 0

Hi team, I have below query. The base query has 440 events returned, But when I use stats command, tje number is 0. Does the because the special charaters in the string to be matched? How should I correct the string? (servername=pc* OR host=pc*) AND sourcetype=access_log_bizx AND "GET /jsup?m=calibrationOrgDataV12*" **| stats count(eval(searchmatch("GET /jsup?m=calibrationOrgDataV12*"))) as number by SFDC**
