Keyword Search in Multiple Columns with Power Query

If you wanted to do a search for keywords in the text of a column or multiple columns you could use the find all feature in Excel. But if this was something where you wanted to bring back the records for those columns that had the keyword and report it back to a stakeholder, you'd want something more complete. Enter Power Query; it can provide the mechanism for you to do keyword search in multiple columns and systematically bring back those rows or records and also take into account the case (i.e., case sensitive words) of the keywords.
