Facets vs. Operators

When to click a facet and when to type an operator

Read first

Day 2 Lab

  1. Run a broad query and open the facet panel beside the results.
  2. Narrow once by clicking a datasource facet; note the result count.
  3. Reproduce that same narrowing by typing the equivalent app: operator.
  4. Decide which felt faster — and whether you'd want to repeat this search tomorrow.
  5. Write the typed version down; that is the form you can save and share.

Working Example: Same Narrowing, Two Doors

A facet click and a typed operator can land on the identical result set. The difference is discovery versus repeatability. Verified against datasource_filters.

Goal: just the Slack results for "incident postmortem"

  FACET path:    type the query → click the "Slack" datasource facet
                 (great when you don't yet know which apps have hits)

  OPERATOR path: type  incident postmortem app:slack
                 (great when you already know — and want to paste it again)

Rule of thumb:
  Exploring an unknown result set?      → click facets, let them show you
  Repeating a search you trust?         → type the operator, save the string

Check for understanding

Name one situation where a facet is clearly better than the equivalent operator, and one where the operator wins.

Check yourself

Pick an answer — you'll see if it's right and why.

1. When stacking operators on a 500-result query, how do you know which constraint did the real work?

2. You're exploring an unfamiliar result set and don't yet know which apps have hits. What's the better tool?

3. A trusted document ranks at #8. What's the honest way to investigate the ranking?

4. What three things must a written search recipe include so a teammate reproduces your exact result set?

5. Which question best justifies Glean's multi-step thinking mode over a quick answer?

“Facets and operators reach the same place by different doors. Click facets to discover what's there; type operators when you already know — and want it repeatable.”
