I have entered some scenarios below, that will hopefully provide the information you are looking for.

- If you are filtering by the first value in the tests name, you will add an asterisk after the value specified in the filter conditions. Example - First_Value*
- If you are filtering by the last value in the tests name, you will add an asterisk before the value specified in the filter conditions. Example - *Last_Value
- If you are filtering by a value in the middle of the tests name, you will add an asterisk before and after the value specified in the filter conditions.
- If there are several tests that begin with the same value, but end with different values, you can use the 'AND' operator. You will add an asterisk after the first value, and an asterisk before the last value in the filter conditions, and it will display only the tests that begin and end with the values specified in the filter conditions. Example - First_Value* AND *Last_Value
- If you use the 'OR' operator in the same scenario above, it will pull all of the tests that begin with the first value specified in the filter ignoring the last value specified in the filter conditions.
- If there are spaces in the test names, you will need to enclose the filter values within single quotes. If there are no spaces, no single quotes are necessary. If you are unsure about the spaces, you can still use the single quotes.

I hope this answers your question.
