Test, validate and match regular expressions
This regex validates specific foundational offering URLs for IBM Watson Health, Merge Healthcare, and Micromedex products. It matches URLs starting with `www.ibm.com` that include either a general hyphenated category or 'products', followed by an exact match to a predefined list of healthcare software and solutions (e.g., `merge-pacs`, `micromedex`). It is highly specialized for filtering, validating, or routing traffic for a specific suite of IBM healthcare product pages.
