This patch fixes a problem where if a staff member sets the
*defaultSortField/*defaultSortOrder system preferences to relevance
ascending while QueryParser is enabled, default keyword search
would break -- the query parser config did not declare relevance asc
as a possible "modifier".
Note that setting the sort order to relevance ascending does not
actually make catalog search return results with the least relevant
records showing up first; Zebra does not support such a mode. In other
words, relevance ascending acts exactly the same as relevance descending.
Test plan:
0/ Create some biblio with "history" in the title and
ensure that the QueryParser system preference is enabled.
1/ Define prefs defaultSortField = relevance and defaultSortOrder = asc
2/ Search "history" on the staff interface
3/ Note that no result is returned.
4/ Apply the patch
5/ Verify the queryparser config file in use takes the modification into
account (see the queryparser_config value in your $KOHA_CONF file).
6/ Relaunch the search and verify results are returned

Remove a line of debug code from EG, provide better error handling
when presented with weird data in the authority linker, and correct
queryparser configuration to reflect the correct configuration for
Zebra.

This patch also corrects the definition of the an= index, which was

Since the most expressive query language supported by Zebra is PQF, this
patch adds a PQF driver for QueryParser which will translate QueryParser
queries into standard PQF (guided by mappings which have been written to
match Koha's existing Zebra configuration) which can then be sent to
Zebra. This driver, Koha::QueryParser::Driver::PQF(::*) extends the
OpenILS::QueryParser(::*) class(es), so as to preserve maximum
interoperability between the various users of the QueryParser driver.
Initially, search syntax is as follows:
* AND operator: &&
* OR operator: ||
* GROUPING operators: ( )
Fields can mostly be searched using the ccl prefixes they have now. The
exception is the various date limits which are searched with a syntax
like this: pubdate(2008)
For sorting, you can simply add #title-sort-az (etc.) to your query.
