A repository object maintained in the ABAP Dictionary. It supplies input fields on Dynpros with single- or multi-column input helps. Search helps can be linked in the Dictionary with components from structures, data elements, and check tables. A search help enables you to search for entry values with assigned data, without you having to know the exact spelling of the value.

please explain in details with step by step process.
create a search help exit:
1. create an fm with this interface:
*" TABLES
*" SHLP_TAB TYPE SHLP_DESCR_TAB_T
*" RECORD_TAB STRUCTURE SEAHLPRES
*" CHANGING
*" VALUE(SHLP) TYPE SHLP_DESCR_T
*" VALUE(CALLCONTROL) LIKE DDSHF4CTRL STRUCTURE DDSHF4CTRL
put this logic in it:
Delete duplicate filter logic.
This logic only needs to apply at the 'DISP' event - which is just
before the hit list is displayed
if callcontrol-step = 'DISP'.
delete adjacent duplicates from record_tab.
endif.
2. edit your search help in se11 and enter the name of the above search help exit fm
