These parameters works together differently based on
on which data type the field in state has. For all fields that are dates (UNPUBLISHED, CREATED, MODIFIED, FIRST_PUBLISHED, DELETED) the fromDate / toDate parameters are used in combination with the state field. So state=MODIFIED&fromDate=08082015&toDate=10082015 will only returned books that are modified in this time period. If not state is given in combination with the date fields MODIFIED will be used as default.
For boolean fields (PUBLISHED, ACCESS) the dateFields have no impact and state=ACCESS will just return all books you have access to.
