Collective.solr

-----------------------------

* Still index, if a field can't be accessed.
[tom_gross]

* Fix the pretty_title_or_id method from PloneFlare; the implementation
was broken, now delegates to the standard Plone implementation.
[mj]

---------------------------------

* Enable multi-field "fq" statements.
[tesdal, witsch]

* Prevent logging of "unknown" search attributes for `use_solr` and the
infamous `-C` Zope startup parameter.
[witsch]

-----------------------------------

* Add logging of queries without explicit "rows" parameter.
[witsch]

* Add configuration to exclude user from ``allowedRolesAndUsers`` for
better cacheability.
[tesdal, witsch]

* Add configuration for effective date steps.
[tesdal, witsch]

* Handle python `datetime` and `date` objects.
[do3cc, witsch]

* Fixed a grammar error in ``error.pt``.
[hannosch]

---------------------------------

* Fix regression about catalog fallback with required, but empty parameters.
[tesdal, witsch]

-------------------------------

* Fix security issue with `getObject` on Solr flares, which used unrestricted
traversal on the entire path, potentially leading to information leaks.
Refs http://plone.org/products/collective.solr/issues/27
[pilz, witsch]

* Add missing `CreationDate` method to flares.
This fixes http://plone.org/products/collective.solr/issues/16
[witsch]

* Add logging for slow queries along with the query time as reported by Solr.
[witsch]

* Limit number of matches looked up during live search for speedier replies.
[witsch]

* Renamed the batch parameters to ``b_start`` and ``b_size`` to avoid
conflicts with index names and be consistent with existing template code.
[do3cc]

* Added a new config option ``auto-commit`` which is enabled by default. You
can disable this, which avoids any explicit commit messages to be sent to
the Solr server by the client. You have to configure commit policies on
the server side instead.
[hannosch]

* Added support for a special query key ``use_solr`` which forces queries to
be sent to Solr even though none of the required keys match. This can be
used to sent individual catalog queries to Solr.
