The search string and searched strings can be unicode strings.
Examples:
Index values return as list:
search("a","abcdabcd");
- returns [0]
search("Л","Л"); //A unicode string
- returns [0]
search("🂡aЛ","a🂡Л🂡a🂡Л🂡a",0);
- returns [[1,3,5,7],[0,4,8],[2,6]]
search("a","abcdabcd",0); //Search up to all matches
- returns [[0,4]]
search("a","abcdabcd",1);
- returns [0]
search("e","abcdabcd",1);
- returns []
search("a",[ ["a",1],["b",2],["c",3],["d",4],["a",5],["b",6],["c",7],["d",8],["e",9] ]);
- returns [0,4]
Search on different column; return Index values:
search(3,[ ["a",1],["b",2],["c",3],["d",4],["a",5],["b",6],["c",7],["d",8],["e",3] ], 0, 1);
- returns [0,8]
Search on list of values:
Return all matches per search vector element:
search("abc",[ ["a",1],["b",2],["c",3],["d",4],["a",5],["b",6],["c",7],["d",8],["e",9] ], 0);
- returns [[0,4],[1,5],[2,6]]
Return first match per search vector element; special case return vector:
search("abc",[ ["a",1],["b",2],["c",3],["d",4],["a",5],["b",6],["c",7],["d",8],["e",9] ], 1);
- returns [0,1,2]
Return first two matches per search vector element; vector of vectors:
search("abce",[ ["a",1],["b",2],["c",3],["d",4],["a",5],["b",6],["c",7],["d",8],["e",9] ], 2);
- returns [[0,4],[1,5],[2,6],[8]]
