Concept chips (suggested related searches) now work in MediaSearch behind a flag. Initial testing indicates that this is a good start but we need to make improvements so that the feature is useful for as many types of searches as possible, with a focus on the most common on-wiki search terms.

Acceptance Criteria:

• Review the list of heuristics/algorithms and determine if any should be discarded.
• Review the list of heuristics/algorithms and determine if some should be ranked/prioritized differently
• Review the list of heuristics/algorithms and determine if additional logic needs to be added to improve relevance of the returned concept chips
• Change the backend implementation of the heuristics so that they don't rely on the Commons Query Service
