Request Type: docs

Impact: small

Complexity: small

**Detailed Description:**

The issue mentioned that searching the docs for fewer than 4 letters didn't return results and wasn't effective for searching smaller topics such as $q or ngIf. The docs were updated to fewer than 3 but this still doesn't include $q. The anchor tag directive still doesn't show up when the user searches for "a" however.

**Other Comments:**

Searching for the anchor tag directive doesn't work when searching "a" but searching "q" returns $q as a result.
