I am trying to search through specific columns in my DataFrame. If any of these columns contains the keyword "Matched" I would then like to write to the column "Result" with a "Yes"

Current DF

```
Result Google    Bing    Search
       Matched   Matched Matched

       Matched   
                         Matched

```

Expected Result

```
Result Google    Bing    Search
 Yes   Matched   Matched Matched
 No   
 Yes   Matched   
 Yes                     Matched

```
