Controlling for PE as a Keyword: Case Sensitivity, Quotation Marks?

I thought I was making good progress with the Keyword approach (vs Score Row), until I hit this One of the "keywords", I am looking for is Private Equity, this works well/if fine. Private Equity is often abbreviated to PE by companies in their LinkedIn descriptions. So I added PE as a keyword And then saw this "huge unexpected result" .... I was flummoxed. The description is written in Bahasa (used in Indonesia and Malaysia) and in Bahasa, there are many words which have the 2 letters pe in them I can think of 2 ways to control for this a) Make it case sensitive as the PE I want is always always expressed in upper case b) Make it look for PE with space before and after (eg do I quote it as " PE " ) Will this work - any other ways?
