RESOLVED - multi search in txt files

Hi!

I have a problem with txt files.

There are may txt files in folder. I need to search a few string in txt files.

For example;

Within each file

"11.10.2016", alex martin, 123456789,500,2500,12000,"london","34100"
"19.12.2016", michael, 8500025122,1500,2500,12000,"paris","06000"
"11.10.2016", jason, 123456789,500,2500,12000,"new york","34100"
"19.12.2016", michael, 8500025122,1500,2500,12000,"paris","06000"

There are thousands of such records.


For example, it scans all .txt files in the folder in "19.12.2016", "12000" and "paris" words . Can I write to another txt file ?

sorry for english

Thank you
