HI All,

     How to pass regular expression to the variable to match command? Please help..

in Following search query we need to pass the value for nonsupporting days dynamically based on the criteria.

| gentimes start=-1 | eval CreateDateEpoch="1412136000" | table CreateDateEpoch | eval start=relative_time(CreateDateEpoch,"@d") | eval end=relative_time(now(),"@d") | eval Date=mvrange(start,end+86400,86400) | convert ctime(Date) timeformat="%+" | eval NoOfBusinessDays=mvcount(mvfilter(NOT match(Date,"(Sun|Sat).*")))

Ex:
eval nonsupport=if(value=1,"(Sun|Sat).*","(Mon|Sun).") | eval NoOfBusinessDays=mvcount(mvfilter(NOT match(Date,nonsupport*))

Thanks
Sathish Rangan
