For the drug API, Elasticsearch is configured to not treat dashes as delimiters. This is a deliberate difference from the glossary API, owing to the fact that drug names contain a lot of punctuation.

Contains searches look for matches at word boundaries. Because we're not treating the dash as a delimiter, the "3-0" in "13-hydroxy-3-0x0-13,17-secoandrosta-1,4-dien-17-oic acid delta-lactone" is not seen as occurring on a word boundary and is therefore not seen as a match.
