Something neat...
I wanted to look up an "Exact Town ID" based on a "Partial Exact Town Name" BUT although I had the entire town name I was searching against a list of Partial town names. So I First found the "Exact Town Name" based on the part (which was actually a partial name since the "master list" is partial names unfortunately)... THEN searched for the "Exact Town ID" based on that Exact town name SO all my Vlookups/Index/Match-whatevers....were set to EXACT ....
=INDEX(county_cheatsheet!$E$1:$E$516,MATCH(VLOOKUP(LEFT(D3,3)&"*",county_cheatsheet!$E$1:$E$516,1,FALSE),county_cheatsheet!$E$1:E$516,0))
The lookup of the "first three letters of the partial town name against the list of partial town names is the MATCH(VLOOKUP(LEFT(D3,3)&"*" part
