I have a package that splits a string to a separate words into array:

CREATE OR REPLACE PACKAGE STRING_FNC
IS

TYPE t_array IS TABLE OF VARCHAR2(50)
   INDEX BY BINARY_INTEGER;

FUNCTION SPLIT (p_in_string VARCHAR2, p_delim VARCHAR2) RETURN t_array;

END;

CREATE OR REPLACE PACKAGE BODY STRING_FNC
IS

   FUNCTION SPLIT (p_in_string VARCHAR2, p_delim VARCHAR2) RETURN t_array 
   IS
   
      i       number :=0;
      pos     number :=0;
      lv_str  varchar2(50) := p_in_string;
      
   strings t_array;
   
   BEGIN
   
      -- determine first chuck of string  
      pos := instr(lv_str,p_delim,1,1);
   
      -- while there are chunks left, loop 
      WHILE ( pos != 0) LOOP
         
         -- increment counter 
         i := i + 1;
         
         -- create array element for chuck of string 
         strings(i) := substr(lv_str,1,pos);
         
         -- remove chunk from string 
         lv_str := substr(lv_str,pos+1,length(lv_str));
         
         -- determine next chunk 
         pos := instr(lv_str,p_delim,1,1);
         
         -- no last chunk, add to array 
         IF pos = 0 THEN
        
            strings(i+1) := lv_str;
         
         END IF;
      
      END LOOP;
   
      -- return array 
      RETURN strings;
      
   END SPLIT;

END;  

To test if it works I use:

DECLARE    
	str string_fnc.t_array;
BEGIN    
	str := string_fnc.split('word1 word2 word3');	

	FOR i IN 1..str.count LOOP	
		DBMS_OUTPUT.PUT_LINE(str(i));
	END LOOP;	
END;

Is there a way to use this package or split function in SELECT such as:
SELECT title
FROM t1
WHERE CONTAINS (title, HERE I PUT FUNCTION('word1 word2 word3')) > 0 ; ?

I mean, for example, If I have table with 4 rows with values word1, word2, word3 and word4 and I run this query without function, I get NO ROWS FOUND, but want to find word1, word2 and word3.
