Motivation and Context (Why the change? What's the scenario?)
Since #684 The PostgresDbClient will fail to return results that match the minSimilarity requirement when multiple filters are used. This is due to how the
WHEREclause is prepared:filter1 OR filter2 OR filter3 AND embedding <=> @embedding < @maxDistancewhich cannot work as expected since theANDoperator takes precedence over theORoperatorHigh level description (Approach, Design)
Simply add parenthesis around the filters argument
