Table schema:
CREATE TABLE table_name_4 (total_matches INTEGER, points__percentage VARCHAR, points_won VARCHAR, year VARCHAR)

Question: What is the total matches in 2002 where points won is larger than 1.5 and the points % is smaller than 50?
SQL: SELECT MAX(total_matches) FROM table_name_4 WHERE points_won > 1.5 AND year = "2002" AND points__percentage < 50
