[hmagrini]

Allow to configure multiple product names for the app to use when searching logs. This feature is backwards compatible.

closes #4

I don't have time to test it. Is it backwards compatible? How does the in operator work when the right side is a string and not an array of strings?

hi @jmarsik!

yes, it's backwards compatible :) The in operator returns True if the substring exists in the string in the right. Conversely, it returns True if the substring is contained within an array. Otherwise, it returns False for both cases https://repl.it/repls/NeglectedCrowdedOperatingsystem

It's not 100% backward compatible because in the current version there is == comparison, not in comparison. Can you change it so that it uses == comparison when the right side is a simple string and in comparison when it's an array of strings?
