Your search results depend on whether the terms you use match the words on the descriptive record of the image, so use combinations of all the words that might apply, connected with OR. For instance:
women OR woman OR girl* OR mother* OR wive* OR ladies OR lady
rural OR pastoral OR farm* OR peasant
royal* OR king* OR queen* OR prince* OR monarch*
Many images lack much descriptive information at all, so you may want to
instead search very broadly for a given place, time period, and classification, to avoid excluding pictures that'd be useful but lack the terms you might search for.
The limiters (Geography, Classification, Date) on the left-hand column are extremely useful for focusing your search.
You need to select your criteria again after every time you change your search terms in the basic search box above your results.
If you edit your search terms instead in the Advanced Search, your limiters will persist.
You can find the link for the Advanced Search directly under the basic search box:
