QueryParser was loading redundant search aliases, which in turn resulted
in certain queries involving two or more clauses joined by a Boolean
operator getting parsed in correctly.
To test:
[1] Enable QueryParser.
[2] Arrange your database so that some some bib records contain
the keyword 'history' while a smaller subset contain
both 'history' and 'earth'. (The exact words used don't
matter.)
[3] Run the following search from the OPAC global search bar:
kw:history && kw:earth
[4] Observe that the records that are returned include *all* bibs
in the database with the keyword 'history'. In other words, the
restriction that the records must also contain 'earth' is not
observed.
[5] Apply the patch and rerun the search.
[6] This time, the results that are returned should include only those
that contain both 'history' and 'earth'.
[7] Verify that prove -v t/QueryParser.t passes.

Passes test plans, all tests and QA script.
Also checked the db_dependent/Search.t tests.
Tried some other searches, all seems to be working correctly.

I reproduce the bug and I confirm this patch fixes it.
Without the patch, kw:history && kw:earth, I got:
Search biblios OK 4 1 1+0 RPN @attrset Bib-1 @attr 4=6 @attr 1=1016 history
With the path, I get:
Search biblios OK 2 1 1+0 RPN @attrset Bib-1 @and @attr 4=6 @attr 1=1016 history @attr 4=6 @attr 1=1016 earth

This patch adds regression tests to verify that
Boolean searches using QueryParser function correctly.
This patch also ensures that QP is correctly initalized
when Search.t is run.
To test:
[1] Apply this patch and the following patch.
[2] Verify that prove -v t/QueryParser.t works
[3] Verify that prove -v t/db_dependent/Search.t works
[4] (optional) instead of applying both patches at the same
time, apply only the regression test patch and run the
tests listed in steps 2 and 3. The following tests
should fail:
t/db_dependent/Search.t (Wstat: 512 Tests: 198 Failed: 2)
Failed tests: 42, 71
Non-zero exit status: 2
t/QueryParser.t (Wstat: 256 Tests: 28 Failed: 1)
Failed test: 12
Non-zero exit status: 1

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.
