Acronyms: Use all capital letters to ensure the search is not looking for that letter sequence instead. (e.g., CIT).

Required term: If a term must be included in any resulting articles, prefix it with a plus sign (e.g., CBP +ruling).

Excluded term: If a term should be excluded from any articles being found, prefix it with a minus sign (e.g., ruling -NY).

Simplest form: Use the simplest form of a term (e.g. "russian export control" instead of "russian export controls") or "entity list" instead of "entity listing" or "entity listed").
