     * Beneficiaries' HICN/MBIs can change over time and those past HICN/MBIs may land in
     * BeneficiaryHistory records. Accordingly, we need to search for matching HICN/MBIs in both the
     * Beneficiary and the BeneficiaryHistory records.
     *
     * There's no sane way to do this in a single query with JPA 2.1, it appears: JPA doesn't
     * support UNIONs and it doesn't support subqueries in FROM clauses. That said, the ideal query
     * would look like this:
     *
     * SELECT * FROM ( SELECT DISTINCT "beneficiaryId" FROM "Beneficiaries" WHERE "hicn" =
     * :'hicn_hash' UNION SELECT DISTINCT "beneficiaryId" FROM "BeneficiariesHistory" WHERE "hicn" =
     * :'hicn_hash') AS matching_benes INNER JOIN "Beneficiaries" ON matching_benes."beneficiaryId"
     * = "Beneficiaries"."beneficiaryId" LEFT JOIN "BeneficiariesHistory" ON
     * "Beneficiaries"."beneficiaryId" = "BeneficiariesHistory"."beneficiaryId" LEFT JOIN
     * "MedicareBeneficiaryIdHistory" ON "Beneficiaries"."beneficiaryId" =
     * "MedicareBeneficiaryIdHistory"."beneficiaryId";
     *
     * ... with the returned columns and JOINs being dynamic, depending on IncludeIdentifiers.
     *
     * In lieu of that, we run two queries: one to find HICN/MBI matches in BeneficiariesHistory,
     * and a second to find BENE_ID or HICN/MBI matches in Beneficiaries (with all of their data, so
     * we're ready to return the result). This is bad and dumb but I can't find a better working
     * alternative.
     *
     * (I'll just note that I did also try JPA/Hibernate native SQL queries but couldn't get the
     * joins or fetch groups to work with them.)
     *
     * If we want to fix this, we need to move identifiers out entirely to separate tables:
     * BeneficiaryHicns and BeneficiaryMbis. We could then safely query these tables and join them
     * back to Beneficiaries (and hopefully the optimizer will play nice, too).
