Are the search enhancements in Web UI 100 % reliable?

Question

Dear Gurus
I have been thinking about this from long time.
I have seen and followed several ways while enhancing Search components (Eg: BT111S_OPPT).
I have a scenario. I am looking for the best possible solution so that it will be 100% reliable.
My scenario:
We know that Oppurtunities have prospects. Prospects inturn have addresses.
I wanted to search Opportunities (BT111S_OPPT) based on "City" of the prospect .
Best solution I found so far  in SDN forum:
In this case, easiest way is to add the "City" to the Search and Result BOL structures,
use some BADI and filter the results.
Now, let us say, I am searching using the city "London".
The standard search returns 100 Opportunities in this BADI (ofcourse without considering the my input city "London").
Now I will start filtering.
Let us say, I don't have any Opportunities (out of these 100) that matches the city "London".
So I am deleting all the 100 results and returning '0' results to the user.
But it doesn't mean that I don't have any opportunities that matches the city "London" in my database.
Those results might be hiding somewhere in the database,  but the standard search is not pulling them,
just because the maximum number of hits = 100 only.
So in this case, my custom query is failing.
Here comes the trickiest part:
Some guys may argue that in the above sceario, after the filtering is done, if I have "0" results,
then I must select all the relevant opportunites using a select statement (based on my city "London" ).
Then execute the standard query again using these Opportunites (to pull the rest of the fields).
This option looks good. But as you know, the user can use any number of search fields.
You know that there will be + button in search screen in Web Ui, where the user can add
as many rows (say 30 rows) as he wants and then select unique field (including my custom field "City")
in each row, enter a value against it and then "Search".
So basically, in case after filtering, if I have "0" results,
when making the select statement to get all the Opportunities,
I have to consider 30 different inputs in this select statement which is very cumbersome.
It will be further complicated if user uses *(asterisks) and ranges.
But if I don't do it this way, my custom enhancement will keep on failing occasionally.  Please suggest your ideas.
Thanks - Raj

Hi,
in the call function of the standard search just comment the line with IV_NUMBER:
CALL FUNCTION 'CRM_BSP_OIC_1O_SEARCH_FROM_RF'
   EXPORTING
     it_search_tab                   = it_search_tab
*     IV_NUMBER                       = IV_NUMBER
*     IV_ARCHIVE                      =
     it_multivalues                  = it_multivalues
*     IV_ITEMS                        =
*     IV_EXTERN_CALL                  =
*     IV_SELECT_FOR_HEADERLEVEL       =
*     IV_CALL_AUTHORITY_BADI          = 'X'
*     IV_FASTSEARCH_ACCESS            = ' '
*     IV_FASTSEARCH_START_ROW         = 1
*     IV_FASTSEARCH_PAGESIZE          =
*     IV_SELECT_FOR_ITEMLEVEL         =
*     IV_AVOID_AUTHORIZATION          =
   IMPORTING
    et_guidlist                     = et_guidlist
    et_return                       = et_return
*     EV_PARTNER_MESSAGE              =
*   EXCEPTIONS
*     DATE_NOT_CORRECT                = 1
*     NO_CARD_TYPE                    = 2
*     NO_CARD_NO                      = 3

Kind regards
