Search tips: in the keyword field, Boolean operators "OR" and "NOT" can be used (eg "tram NOT train" or "tram OR train"). By default, spaces in searches work as a Boolean "AND" (eg "tram train" searches for records where "tram" and "train" occur).
Terms can be entered in the "Advanced Search" fields on their own or to delimit keyword searches.
Date ranges can be searched using the format "1880-1885".
