10. The computer-implemented method of claim 9 , wherein the unsuitable ER candidate-building key is disqualified from ER candidate building, so as to facilitate removal of the unsuitable ER candidate-building key from one or more subsequent queries, prior to execution of the one or more subsequent queries, wherein one or more modified subsequent queries are generated, wherein execution of the query is aborted upon determining that the first ER candidate-building key is unsuitable comprises determining that a predefined unsuitability condition is satisfied.

The computer-implemented method of claim 10 , wherein the method is performed by an identity resolution application, wherein the identity resolution application is configured to determine that the first ER candidate-building key is unsuitable based on each predefined unsuitability condition of:: (i) a first unsuitability condition comprising the first ER candidate-building key retrieving a count of candidate entities beyond a first predefined threshold count; (ii) a second unsuitability condition comprising the first ER candidate-building key retrieving a count of candidate entities beyond a second threshold count subsequent to retrieving the first predefined threshold count of candidate entities; and (iii) a third unsuitability condition comprising the first ER candidate-building key and a second ER candidate-building key each retrieving a respective count of candidate entities beyond a respective predefined threshold count.
