Hi Yogesh,
Text facet is a convenient way to manually select values. If you want to batch select them based on a pattern, there are other methods. It all depends on what you are looking for.
For example, if it's string lengths too short or too long, use Text Length Facet or Text Length log. If these are cells that contain certain words or special characters, Text Filter (and possibly a regex) will allow you to select them all at once.
I guess that you are trying to select the values for which there are fewer than five occurrences. In this case, you can add a column based on your column MAILINGCOUNTRY and use these Grel formula :
facetCount(value, "value", "MAILINGCOUNTRY")
You can then apply a "Numeric Facet" on this column to select all rows less than five.
