NodeNorm ES fails to return some identifiers when drug_chemical_conflate is turned on

[gaurav]

Something is weird with drug_chemical_conflate: when I run this query on NodeNorm Redis, I get 146 CURIEs:

• https://nodenorm.ci.transltr.io/get_normalized_nodes?curie=UMLS:C0106127&curie=CHEMBL.COMPOUND:CHEMBL221542&curie=PUBCHEM.COMPOUND:222284&drug_chemical_conflate=true

However, NodeNorm ES only returns 32 CURIEs:

• https://nodenorm-es.ci.transltr.io/get_normalized_nodes?curie=UMLS:C0106127&curie=CHEMBL.COMPOUND:CHEMBL221542&curie=PUBCHEM.COMPOUND:222284&drug_chemical_conflate=true

With drug_chemical_conflate turned off, both services return 17 identifiers each:

• https://nodenorm.ci.transltr.io/get_normalized_nodes?curie=UMLS:C0106127&curie=CHEMBL.COMPOUND:CHEMBL221542&curie=PUBCHEM.COMPOUND:222284&drug_chemical_conflate=false
• https://nodenorm-es.ci.transltr.io/get_normalized_nodes?curie=UMLS:C0106127&curie=CHEMBL.COMPOUND:CHEMBL221542&curie=PUBCHEM.COMPOUND:222284&drug_chemical_conflate=false

@gaurav it seems that CURIEs returned by the CI servers are repeating a lot - for example CAS:76772-70-8 appears 6 times in the results. If we count unique CURIEs only there are 32 of them, matching what we got from ES CI. Could this be an undesired artifact of the Redis version?
