And the #editions/page is increased to 50 and the #pages is limited to 10. Pagination is now by Older/Newer links.
The isbn_ field indexes both ISBN-10 and ISBN-13 fields.
This allows querying for isbn-13 even when the edition page has just isbn-10 defined.
When there are too many seeds in a list, the query to get data from couchdb-lucene becomes too big to make a GET request. Fixed this issue by making multiple couchdb-lucene queries with 50 seeds in each request. The response was earlier sorted by last-modified. To maintain the same behavior, the edtions got from multiple queries are sorted by last-modified in descending order before converting them to appropriate export format. The "activity" tab still gives internalerror for the same reason. This needs to be handled separately.
