-- A query term is either:
--
-- 1. a search pattern, which matches on one or more fields, eg:
--
-- acct:REGEXP - match the account name with a regular expression
-- desc:REGEXP - match the transaction description
-- date:PERIODEXP - match the date with a period expression
--
-- The prefix indicates the field to match, or if there is no prefix
-- account name is assumed.
--
-- 2. a query option, which modifies the reporting behaviour in some
-- way. There is currently one of these, which may appear only once:
--
-- inacct:FULLACCTNAME
--
-- The usual shell quoting rules are assumed. When a pattern contains
-- whitespace, it (or the whole term including prefix) should be enclosed
-- in single or double quotes.
--
-- Period expressions may contain relative dates, so a reference date is
-- required to fully parse these.
--
-- Multiple terms are combined as follows:
-- 1. multiple account patterns are OR'd together
-- 2. multiple description patterns are OR'd together
-- 3. multiple status patterns are OR'd together
-- 4. then all terms are AND'd together
