Comment 1 for bug 1440777

Hello and thanks for the report.

For some background, here is how your "1+1" search is normally handled by the dash.

If you have online search enabled (System Settings -> Privacy -> Search), it just works, but your query is sent to a server hosted by Canonical, which purpose is to correlate queries with scopes to make the Dash smarter:
- the dash sends "1+1" to dash.ubuntu.com
- the server notices the query is a calculation (or a band name, or a github project, etc)
- it sends back to the dash a list of scopes it should activate for this query
- the dash activates the calculator scope and gives you an answer

If you don't:
- The dash tries the 1+1 query on "always search" scopes (files, music, applications).
- and waits for sources to be manually enabled

That doesn't help you, but I think it's useful to have an overview of how the Dash works when interacting with it. Now, you have two ways to directly invoke the calculator scope:

1) Using a keyword: eg. "calc:1+1" or "result:1+1"

2) or adding the calculator scope to the list of "always search" scopes (using dconf-editor, you can find it in "com.canonical.Unity.Lenses").
