That Delaware database doesn't have an entry for every previous name of a company - just the most recent name.
This is not complicated. Searching for just AMDL on that search page should make this point sink home. Here's what you see:
FILE NUMBER ENTITY NAME
3435698 AMD LATIN AMERICA, LTD.
4627207 AMDL DIAGNOSTICS, INC.
3666555 AMD, LLC
2139062 A.M.D. LOUISIANA MARINE, INC.
Notice that AMDL INC does not come up. Neither does CALIFORNIA VENTURES INC, Radient's original corporation name when they sold check blanks before 1989.
Radient Pharmaceuticals only comes up under the name Radient Pharmaceuticals, the corporation's most recent name.
Hemiwedge is file number 3517367 and the most recent name is HII TECHNOLOGIES, INC. It won't come up under a search for Hemiwedge because that is not the most recent name.
I can't explain it any simpler.
