Search in internal table utility

Question

Hi Experts,
As per my requirement we need a utlity i.e a  class or F.M  which search for a "Word" or "Phrase" in fields of internal table and display the internal table output  based on there ranking.
For example:
Search term in internal table is:          Novartis  Global  
My Internal table has records like this:
ITAB
FIELD1                                FIELD2                                   FIELD3                  LINE
Novartis Global                   xyz                                        Global                    1
ABC                                  Novartis                                   DXY                       2
Novartis Global                Novartis Global                        Novartis Global       3
1020                                  EWR                                       Globaling                 4
My O/p should be
FIELD1                                FIELD2                                   FIELD3                    LINE
Novartis Global                Novartis Global                        Novartis Global         3
Novartis Global                   xyz                                        Global                       1
ABC                                  Novartis                                   DXY                          2
1020                                  EWR                                      Globaling                     4
For achieving this i used command
FIND ALL OCCURRENCES OF Novartis  Global     IN TABLE ITAB  RESULTS IT_RESULTS  IN CHARACTER MODE .
Since all records in my internal table have the search term already it retunrs all the records but i want to RANK these records
based on my search term
1.Records which exactly match the keyword in all fields should be first
2.Records which have the key word in atleast 1 field should be second
3.Records which have one word of 2 should be third
and so on RANKING BASED on search term.
Please suggest how should i go about it ? I am not sure what kind of logic is required here.
Any suggestions will be appreciated.
Thanks

TYPES: BEGIN OF ty_data,
        f1 TYPE char30,
        f2 TYPE char30,
        f3 TYPE char30,
        line TYPE i,
       END OF ty_data.
DATA:
lt_data TYPE TABLE OF ty_data,
wa_data TYPE ty_data,
mcnt TYPE i,
moff TYPE i,
mlen TYPE i,
lv_f1 TYPE i,
lv_f2 TYPE i,
lv_f3 TYPE i.
LOOP AT lt_data INTO wa_data.
  lv_f1 = 0.
  lv_f2 = 0.
  lv_f3 = 0.
  FIND ALL OCCURRENCES OF wa_phrase IN wa_data-f1 IN CHARACTER MODE
  RESPECTING CASE MATCH COUNT  mcnt
  MATCH OFFSET moff
  MATCH LENGTH mlen.
  IF sy-subrc = 0.
    lv_f1 = 1.
  ENDIF.
  FIND ALL OCCURRENCES OF wa_phrase IN wa_data-f2 IN CHARACTER MODE
  RESPECTING CASE MATCH COUNT  mcnt
  MATCH OFFSET moff
  MATCH LENGTH mlen.
  IF sy-subrc = 0.
    lv_f2 = 1.
  ENDIF.
  FIND ALL OCCURRENCES OF wa_phrase IN wa_data-f3 IN CHARACTER MODE
  RESPECTING CASE MATCH COUNT  mcnt
  MATCH OFFSET moff
  MATCH LENGTH mlen.
  IF sy-subrc = 0.
    lv_f3 = 1.
  ENDIF.
  lv_f1 = lv_f1 + lv_f2 + lv_f3.
  IF lv_f1 = 3.
    wa_data-line = 1.
  ELSEIF lv_f1 > 0.
    wa_data-line = 2.
  ELSE.
    wa_data-line = 3.
  ENDIF.
  MODIFY lt_data FROM wa_data TRANSPORTING line.
ENDLOOP.
SORT lt_data BY line.
LOOP AT lt_data INTO wa_data.
  WRITE:/ wa_data-f1, wa_data-f2, wa_data-f3, wa_data-line.
ENDLOOP.
CLEAR wa_data.
Hi,
The above code will sort the table for 1st and 2nd Rank properly. There is still logic to be added for 3rd Rank. The phrase should be split in words and then each word should be searched in each field of internal table and thus derive if its for 3rd Rank or not.
