* Elastic Search Surname : *Search the surname component from the query constellation against all surnames from SNAC identity constellations. Return the top N constellations based on Elastic Search's search algorithm with Elastic Search native scores as the stage score for each candidate constellation.*
* Elastic Search Forenames : *Search the forenames component from the query constellation against all forenames from SNAC identity constellations. Return the top N constellations based on Elastic Search's search algorithm with Elastic Search native scores as the stage score for each candidate constellation.*
* Exist Dates : *Search the exist dates from the query constellation against all identity constellations in SNAC. Return all constellations that contain the exact exist dates as the query constellation.*
* Fuzzy Exist Dates : *Search the exist dates from the query constellation against all identity constellations in SNAC. Return all constellations that contain exist dates within a range of X from those in the query. Stage score is defined as the distance from the query's dates, lower is better.*
* Occupation : *Search the list of occupations from the query constellation against all identity constellations in SNAC. Return all constellations that match all occupations in the query constellation. (The candidates must have the entire list of occupations from the query as a subset of their occupation list.)*
* Place : *Search the list of places from the query constellation against all identity constellations in SNAC. Return all constellations that match all places in the query constellation. (The candidates' list of places must be a superset of the query constellation's places.)*
***Candidate Constellation list modifying stages***These stages take lists of candidate constellations and modify or replace the scores for the input results.*
* Name Entry Length : *Compute the difference in length between the candidate constellation's constructed name entry string and the query constellation's constructed name entry string. Replace the original stage score with the log of the difference.*
* Name Entry Length : *Compute the difference in length between the candidate constellation's constructed name entry string and the query constellation's constructed name entry string. Replace the original stage score with the log of the difference. Lower scores are better.*
* SNAC Degree Sort : *Replace the original stage score with the number of constellation relations (constellation out-degree) in the candidate constellation. Constellations that are more connected with other SNAC identity constellations will get better scores.*
* SNAC Resource Count Sort : *Replace the original stage score with the number of resource relations (resource out-degree) in the candidate constellation. Constellations with higher resource relations will get better scores.*
***Multi-Stage***This stage allows the execution engine to run multiple stages in sequence, feeding the results of one stage as the input to the next. It results in one final list of candidate constellations from all independent stages it ran.*
