New authority level configs

service_uri - the uri for the authority provider that allows the service to send general information as part of a search query or term fetch

New search level configs

total_count_ldpath - the ldpath within the results graph that holds the total number of available search result records. The service_uri will be the subject URI of the triple holding this value.

configs in qa_replacement_patterns subsection

These configs identify parameters that are passed to QA and play a specific role.

start_record - number of the first record returned in search results
requested_records - number of records to return in search results

Using configs for pagination support

start_record and requested_records are used to identify the page number and the number of records to display on a page. For example...

start_record = 1 AND requested_records = 10 equates to page 1 records 1..10
start_record = 11 AND requested_records = 10 equates to page 2 records 11..20
start_record = 21 AND requested_records = 10 equates to page 3 records 21..30
etc.

The total number of pages can be calculated by getting the total number of search results from triple...

<service_uri> <total_count_ldpath> total_count .

number_of_pages = total_count / requested_records
