Hierarchical search

Hierarchical search lets you use the > search operator to filter items based on the content of their parent nodes. In other words, it lets you use information about the parent node of the item you're searching for to filter it.

Here are two examples demonstrate how the search works and how you might use it.

Example 1 - Vehicle wiki ↗
Example 2 - Web agency ↗

Perform a hierarchical search 

1. Click the search bar or press 'esc' on your keyboard
2. Write a string or property (like is:complete) to specify something about the parent of the item you're searching for
3. Type the > search operator to turn the search into a hierarchical one
4. Write a string or property you're trying to filter
5. (optional) Continue using > to narrow down your search even further 

Example 1 - Vehicle wiki

Here's a wiki of vehicle types, makers, and manufacture years.

Say you wanted to see all the "Honda" vehicles for the year "2023".

You can do this with a hierarchical search of "honda > 2023"

And here's what that search looks like.

Only items that match "2023" that also have a parent node of "Honda".

We could narrow down the search even further by adding another hierarchical search to filter out only the cars with a search of "cars > honda > 2023".

Example 2 - Web agency

In this example we have a list of projects for a web agency.

Say we want to see all tasks assigned to a team member "@sam".

This search would show us all the todos for "@sam".

And if we wanted to narrow down the search and only look at the SEO related tasks, we could do that with a hierarchical search of "SEO > @sam".

We could narrow down the search even more by specifying we only want to include projects that are "#high" priority with a search of "#high > SEO > @sam".
