Broker use

'BROKER USE' Syntax: LOCATE [options] bid <gold amount>

There are many options. Use only what you absolutely need, since over-
specifying an item will make it difficult or impossible to locate. Valid
specifiers are: TYPE, WEIGHT, WEARFLAGS, EXTRAFLAGS, AFFECT, MATERIAL,
PREFERENCE, LEVEL, SPELL, CHARGES, DAMAGETYPE, AVG, and AC. Note that
not all specifiers are used for all item types. Mish will happily
accept any impossible combination that you specify, such as weapons
with spells. For more help on these specifiers, see HELP BROKER <specifier>
(e.g. HELP BROKER TYPE, HELP BROKER SPELL). The options can be
specified in any order, and can often be abbreviated. In most cases,
each option should only be specified once. WEARFLAGS and EXTRAFLAGS
are the exceptions.

For example: LOCATE AFFECT DAM 3 BID 40000 indicates that you will pay
40,000 gold for a +3 damage item, regardless of item type or wear
location. LOCATE TYPE WAND SPELL CONFUSION CHARGE 3 LEVEL 25 BID 10000
specifies that you are looking for a wand with level 25 confusion and
at least 3 charges, and that you will pay 10,000 gold for it.
