Hi,
These 3 definitions exist in the English (India) locale for the current version of the QKB.
They are documented here:

Name definition is the most basic. I wouldn't use it for long strings that have more tokens than just a first and family names.
Name with Extensions can handle much longer input strings, with Extensions, Middle Names, etc. This is the one I would use for what you describe.
The Name with Combinations is a different type of Matching definition: Combination-based match definitions create multiple match codes for a single input string by manipulating the tokens of the input string with token combination rules.
See more information here:

Hope this helps.
Thanks,
Audrey
