Is there a way to order filter results by the 'most relevant' result.

RoadRage

For example we have a value "Unclassified" that always appears at the bottom when a user searches "un" due to the default order being ascending. As "unclassified" includes the characters "un" earlier in the string than, say, "duncan" I'd like it to appear at the top. All of the examples I've been looking at apply custom sorting to the table regardless of whether or not it has been filtered.
