I assumed they were letters, but I can't get the field to behave the way I want (which is to have it support infix searches, like searching for "ethylpre" should match "methylprednisolone").

Shingles are [based on words](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/analysis-shingle-tokenfilter.html). What you are looking for is probably [ngrams](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/analysis-ngram-tokenizer.html).
