Devices, systems, and methods for improving results returned from a query. A method can include identify, based on a term embedding of a corpus of terms, expansion terms of a raw query term that are nearest the raw query term, normalize distances between the raw query term and the identified expansion terms, identify, based on the term embedding, expansion term neighbors of an expansion term that are nearest the expansion term; normalize distances between the expansion term and the identified expansion term neighbors, determine a WMA weight between the raw query term and the expansion term, and execute the query with the raw query terms and the expansion terms (determined based on the WMA weight) to generate query results.
