autoComplete - Limit results to exact spelling of partial address

**Scenario:**
- The client is building a web application that will use autoComplete to provide a location search feature.
- Users of the web application will use autoComplete to search for civic addresses, localities and streets.

**Issue:**
- When users provide a partial address that does not contain a civic number (locality or street search), the results can be broad due to the number of possible matches, aliases, spell check etc.

**Task:**
- Introduce a new boolean parameter that can be used in combination with autoComplete (name tbd: perhaps 'exactSpelling').
- If true, the resulting list of suggestions will begin with the partial address.
- Default value is false
