Minor trick to make the code easier to read and maintain:
WHERE COALESCE (title1, title2, title3) IS NOT NULL
OR COALESCE (ggregation_title1, aggregation_title2,
aggregation_title3, aggregation_title4) IS NOT NULL
Unfortunately these columns look like repeated and a really bad 1NF
problem. I have the feeling that you might have wanted to use
COALESCE() in the SELECT list to get a non-null title and non-null
aggregation_title instead of this convoluted query.
