Help the user out with search suggestions

[charlesreid1]

There are two ways to provide a user with suggestions:

• "Did you mean...?" and using a wordlist/dictionary to check for common misspellings
• Autocomplete drop-down box

Centillion provides the former, but not the latter.

To implement the latter, may need to build a separate keyword search index, as suggested in this SO answer. Would also need to implement Javascript + API call to get lookahead suggestions.
