Show how to use document properties to filter on searches.
If you search for a term like "Role" or "Stakeholder" you'll get plenty of hits. This is because the Core Doctypes provide doctypes with this name. For each space there may be a home page and an index page for each of these doctypes and these pages also contain the string "Role" or "Stakeholder".
In addition to those, there are also home pages and index pages for the corresponding type doctype, like "Role Type" and "Stakeholder Type". So these pages will also clutter your search result.

The result set above shows a number of home pages for Role Types.
Two Kind of Pages
There a two kind of pages in a Confluence site: destination pages and navigation pages.
Destination Pages
A destination page is a page contains actual relevant information. It is something like a description, an open issue, a service, a role, or a stakeholder.
Destination pages why a space has been created.
Navigation Pages
A navigation page has only one purpose. It holds links of some kind and enables users to browse pages. Navigation pages are important to organize and find pages, but no space would be created only for navigation pages.
Home page and index pages typically have only navigation purposes. Readers know where to look for a list of roles or the address book of stakeholders.
When searching for "Role" or "Stakeholder" these navigation pages should not show up as search results.
Filter Navigation Pages
Confluence does not distinguish between destination pages and navigation pages. There is only the concept of a page.
The projectdoc Toolbox provides navigation pages by the doctype named docsection
.
This makes it easy to remove these pages from the search results!
Instead of
you would type the following:
"Role" -Doctype: docsection

Now Confluence will only return destination pages related to "Role" and remove all navigation pages from the result set.
The Doctype property is almost like any other property. The same way you filter on the Doctype property you could chose any other property or combination of properties to put constraints on a search.
"Role" +Severity: High +Doctype: task
A Confluence site consists of a number of spaces. Within a space home pages and index pages provide navigation support to users. They make it easy to browse documents of a given type and find related information.
Besides navigation page as space's main purpose is to server destination pages. In searches user typically want only destination pages in their result set.
To remove navigation pages add -Doctype: docsection
to your search query.
