I think you misunderstand APARs because you question doesn't make sense.

1. APARs are PTFs that are very rarely created and never required to be applied.
2. Most product developers will never write an APAR write an actual APAR 
because the problem must be so serious that a customer can't wait for the PTF 
solving the problem described in the APAR.
3. Unlike PTF's, most vendors use the same APAR number tailoring the APAR fix 
specific to each customer that needs it. For example, problem spans multiple 
versions of the product or maybe tailored specific to the customers 
environment. In contrast, a PTF is specific to a release and is the same for 
all customers using that release.
4. The resolving PTF will always SUP the APAR. An SMP/e search for the APAR is 
sufficient but you must verify the APAR has been SUP'd. An applied APAR is 
considered a very temporary fix that may not completely resolve the problem. 
5. Choosing an APAR number is completely flexible. The only requirement is to 
avoid SMP/e collisions. The same APAR number cannot occur multiple times in an 
SMP/e zone (global, target or dist).
6. The APAR number choice has no real significance except how a product has 
chosen to avoid SMP/e collisions. For instance, you say AHxxxx went to PHxxxxx, 
In the past, this told me that IBM probably acquired a vendor product. Anything 
beginning with I to Z was reserved for IBM use (e.g. IEFJRASP, OA12345, 
UA12345). I suspect that most vendors use the IBM registry for 3 character 
codes from A to H. Each product must choose a method that best fits the company 
requirements.

What are you "searching for"? In general, APAR numbering schemes does not have 
anything to do with a search. Either you have a specific APAR number or you are 
searching for an APAR number. In the past, APAR numbering had no meaning except 
for internal use. 

In the past, CA and EA would have been non-IBM APARs. Only the company 
producing these apars can tell you what they mean. For instance, a company 
could choose to use CA apars for multiple products.
