Facet display and functionality

LOGIC

• By default all the filters are unselected, unless the user arrives with a 'canned query'
• All facets use AND logic by default (ie. they filter down the result set)
• The position of each facet block remains the same regardless of selected filter
• The selected values within each facet block should remain (post selecting/display of results)
• Ordering of values within each fact block should be by count
• Selecting filters of one category influence/filter the other filters of the other categories

VALUES & ORDER

ALL / OBJECTS FACETS

• Category
• Date
• Maker
• On display (i.e. museum location) [1]
• Object type
• Place
• Images [Commercial : Non-Commercial] (this filter/facet should allow users to restrict the result set to a) records with a CC licensed image ie. non-commercial or b) those with an image, but that isn't CC licensed ie. commercial) [2]
• User (note: it is likely that this will be dropped for launch; but for testing it would be useful to have)

​[1] On Display, should list the following values

• Science Museum
• National Railway Museum
• National Media Museum
• Museum Science & Industry

​[2] Images, should list the following values

• Commercial
• Non-Commercial

PEOPLE FACETS

• Occupation
• Date (born / died) [1]
• Place born
• Organisation / Person

[1] there should just be one date selector (to-from) that matches if either the born or died date falls within it's range, ie. was this person or company active between these two dates

DOCUMENTS

• Archive ('fonds' name) [1]
• Format
• Date
• Creator
• Type
• Place
• Organisation
• Images (i.e. as above re. Non-Commercial / Commercial mapping to records with CC licensed image)

[1] Archive - I suspect these will be unusable due to length, but be interesting to see for testing.
