Coverage cleanup #118
This contains several changes:
- bring back
issued-year
field, used to break down by issued year for coverage - use correct field in
type-name
facet transformer - make sure that journal metadata does not contain
counts-type
field, andcoverage-type
field is not broken down by content type - make sure
coverage
index contains only the latest coverage object for every member and journal - when open references fraction is calculated for a member/journal, it uses list of open prefixes calculated once for thee entire coverage task (for performance reasons)
- when statistics for content types are calculated for a member/journal, only relevant content types are processed (for performance reasons)
- use offsets for processing the entire members and journals sets
