Hi Mouni,

To learn how PDN Search works, see Essential Links on the PDN, the topic PDN Search.

Here are some PDN starter links to the product topic categories that you listed along with a Search tip for each one.

[Node IDs are the permanent link ID. Title-based URLs are subject to link breakage. Help topics do not have Node IDs. When I want authoritative information, I filter my PDN SERP on a Pega Platform Version and Content Type = Help topic]

Ruleset

Tips: From this article, see the Index to learn what product category "ruleset" belongs to -- Reuse and Version Management. Look at the other topics in  Reuse and Version Management to learn how product content is organized. Use your PDN Search Results, adjusting various filters, to learn other contexts for "ruleset".

Tips: Validation has many contexts.

Search PDN on "Validation" and filter the results to Exclude Forums and select Pega 7.x.

Also play around with the SERP filters to see how Rule Resolution is documented for different application development contexts.

Tip for your future postings: Fewer categories. More tags. Apply one category, no more than two categories. Use lots of tags.
