Regex - exclude search results

I am looking for my changes in log file. Here is example:

"2-11-2016 11:39:27 CET","[email protected]","Changed Class1 Apex Class code","Apex Class",""
"2-11-2016 12:39:27 CET","[email protected]","Changed Class2 Apex Class code","Apex Class",""
"2-11-2016 13:39:27 CET","[email protected]","Changed Class2 Apex Class code","Apex Class",""
"2-11-2016 14:39:27 CET","[email protected]","Changed Class1 Apex Class code","Apex Class",""
"2-11-2016 15:39:27 CET","[email protected]","Changed Class3 Apex Class code","Apex Class",""
...
"2-11-2016 15:39:27 CET","[email protected]","Changed FirstClass Apex Class code","Apex Class",""
"2-11-2016 15:39:27 CET","[email protected]","Changed SecondClass Apex Class code","Apex Class",""

I already know that I changed Class1 and Class2. So I need to find another classes that I changed (SecondClass in this example)

how to create regex to exclude Class1 and Class2? I use search in Sublime Text

It appears you need to match some string that is not followed with a number (that you are going to add manually after each match) as a whole word.

You may use a negative lookahead based regex with a group of alternatives (...|...|etc.) and a word boundary \b:

"[email protected]","Changed Class(?!(123|12|1|2|3)\b)
|
---------- a known part --------------------|negative lookahead|

The negative lookahead fails the match if the known part is followed with 123, or 12, etc. followed with a word boundary (see (123|12|1|2|3)\b). The capturing group can be replaced with a non-capturing one that is only used for grouping: (123|12|1|2|3) => (?:123|12|1|2|3) (meaning it won't put any subtext into $1, Group 1).
