Where to define Query Rule and when?

Question

We can define Query rule in three places:

1. Search Site > Site Settings > Search > Query Rules
2. Search Site > Site Settings > Site Collection Administration > Search Query Rules
3. Search Service Application > Queries and Results > Query Rules

What is the difference in all of above options? Which option is appropriate in what situation?

Answer 1

The scope of the rule:

• If you define them in the search service, its valid for all webapplications associated with that search service.

• If you define it on subsite/web level, its valid for the contextual search made on that site.

• If you define it on site collection its valid for the site and all subsites.
