Informix Query Engine generates bad query/explain plan

There are situations where two or more columns from the same table are related to each other. For example, product_type and product_code from the products table are related, since only certain product_code values can be associated with a given product_type. There are frequently queries that have filters on both columns at the same time, e.g., product_type = 'HG' and product_code = 135. When correlation exists such combination of filters on related columns often results in inaccurate estimates from the Informix optimizer, leading to bad query plan.
