wouldn't it be easier to do ?

index="real" Location="*mumbai*"

index="real" Location="*delhi*"

index="real" Location="*kol*"

OR if you dont have many values

index="real" | rex field="Location" (?<target>(mumbai|delhi|kol)) | search target=mumbai

but my output should come like this :

Name,age,company,target
xyz,45,kolkata,kolkata
xyz,45,kolkata is a mumbai,kolkata mumbai
xyz,45,ludhiaya
xyz,45,delhi, delhi

xyz,45,bangalore

"target" will be added as a last column and the matched keywords will be the value

Please help
