This score is not the same as in the input. UR calculates LLR between item pairs and leaves only pairs that pass threshold. This is stored in ES as documents with item as id and correlated items tokens as text (item -> (item,item,...)). UR makes a query to es with its own item list (for example, user history). After that es considers it as a document with your query items (its text content) and finds nearest neighbors from texts distance (tf-idf). the resulting score is just texts similarity from es
