Make search return results for can.X

[chasenlehara]

If someone searches for something like can.component, I think it’d be helpful if they found the can-component docs. Right now, nothing is returned for that query (in the v4 docs).

This is really helpful in the v3 and v4 docs (because the recipes still show can.Component)… it’ll be less important in v5, but I think it’d still be nice to have.
