May I ask here, reading the first time on these things,
for additional information!?
[A question as a(n applying) mathematician etc.,
  not so much about TeX.]
What is the point of searching for parts of formulas?
Primitive counter-example:
$e^i$ may appear where e is the Euler constant and i that
imaginary square root of -1; or e may be anything and i a
non-negative integer.
Moreover, sometimes same things are expressed by different
notations. E.g., in order theory there are standard terms
like `poset', `linear order', `interval order', `semi-order'
(good enough for searching)
where the basic relation may be notated as `P', `R',
`<' or \lesseq, \prec ...
-- May be in certain areas there are standard notations
and certain exponents or the like classify sub-areas ...
