If you are certain of part of the name(s) in this case let's say you know the parents are called "Angel XXXX" and "XXXX toshie" then you just put in "angel%" in the first field and "%toshie" in the second and presto!

In the case you mention Kerry, the problem might be that the RHS search also recognises if a space is made after the grex name. If for instance the guy typing in the grex "little toshie" accidently typed "little toshie " (with a space after "toshie") then you wont be able to find the plant by just typing the grex name as you normaly would. <- did that make any sence??
If you remember a particular cross you once had a problem with Kerry, try doing a search with "%" on both sides of the parent grex names, could be interesting to see if it works
