        SilvaFind
        =========
        
        SilvaFind is a powerful search feature to allow easy creation of search forms
        and result pages, both for users of the public site and for authors in the SMI.
        Simple schemas can be defined to indicate which fields should be searchable.
        
        Authors can add a *Silva Find* object anywhere and define which fields to
        make searchable by end users of the public site, and/or which fields to
        limit to a preset value. Authors also can determine which fields should be
        displayed in the search results. All metadata set/fields are supported.
        
        If you can't add the *Silva Find* object in the SMI you should make sure it's
        checked in the *addables* section of the publication. If Silva Find is not
        checked, check it and uncheck the inheritance checkbox (otherwise inheritance
        will overrule it and uncheck it again).
        
        By default all possible custom search criterion fields and result fields are
        available in the SMI. Besides that, the elements of all metadata sets are also
        available as result fields. If these fields are indexed in the catalog, they
        can also be used as search criterion fields. All available fields can be
        enabled/disabled in the SMI.
        
        Besides this behavior, SilvaFind also allows you to manually override the list
        of search criteria. This behavior is also intended for backwards compatibility,
        but can be used to add your own custom fields from within other products.
        
        For example the default global schema that SilvaFind installs
        (``globalschema.py``) looks as follows::
        
        from Products.Silva.i18n import translate as _
        
        from Products.SilvaFind.schema import SearchSchema
        from Products.SilvaFind.schema import ResultsSchema
        
        from Products.SilvaFind.schema import ResultField
        from Products.SilvaFind.schema import FullTextCriterionField
        from Products.SilvaFind.schema import MetadataCriterionField
        from Products.SilvaFind.schema import MetatypeCriterionField
        from Products.SilvaFind.schema import DateRangeMetadataCriterionField
        
        globalSearchSchema = SearchSchema([
        MetatypeCriterionField(),
        FullTextCriterionField(),
        MetadataCriterionField('silva-content', 'maintitle'),
        MetadataCriterionField('silva-content', 'shorttitle'),
        DateRangeMetadataCriterionField('silva-extra', 'publicationtime'),
        ])
        
        globalResultsSchema = ResultsSchema([
        ResultField('get_title', _('Title')),
        ])
        
        The result schema defines what fields get shown in the list of results, by
        default as columns in a results table. There are currently 3 types of
        result fields (plain vanilla, metatype and metadata), and it is not hard to
        make your own. See schema.py for how that is done.
        
        The following SearchField types exist for now, and of course it is possible
        to roll your own:
        
        ``MetatypeCriterionField``
        allows the content that is to be searched, to be restricted to
        certain (one or more) content types.
        
        ``FulltextCriterionField``
        allows the fulltext of the content item to be searched.
        
        ``MetadataCriterionField``
        allows a specific metadata field of a specific metadata set to be
        searched.
        
        ``DateRangeMetadataCriterionField``
        allows a specific datetime based metadata field of a specific
        metadata set to be searched, using a date range.
        
        ``PathCriterionField``
        allows the content that is to be searched, to be restricted to be
        below a certain path. The path of the found children will always
        start with the supplied path, which is a string starting from the
        site root.
        
        Making your own is as simple as creating a different SearchSchema and
        ResultsSchema in your extension, and registering it in the install.py of
        your extension. You can replace the global default search schema as
        follows, assuming myOwnSearchSchema is a valid SearchSchema object::
        
        def register_search_schema(root):
        root.service_find.search_schema = myOwnSearchSchema
        root.service_find.manage_delObjects(['default'])
        SilvaFind.manage_addSilvaFind(
        root.service_find, 'default', 'Default search')
        default = root.service_find.default
        for field in root.service_find.getSearchSchema().getFields():
        fieldName = field.getName()
        default.shownFields[fieldName] = True
        default._p_changed = True
        
        If your extension defines its own metadata-set, making the fields in
        that set searchable by putting them in your schema is easy::
        
        myOwnSearchSchema = SearchSchema([
        
        ...
        
        MetadataCriterionField('my-metadataset', 'my-field1'),
        MetadataCriterionField('my-metadataset', 'my-field2'),
        
        ...
        
        ])
        
        For a good example of how to customize and use SilvaFind from your own
        extension, see the Silva DLCMS, which you can find here::
        
        svn co https://infrae.com/svn/dlcms/SilvaDLCMS/trunk/ SilvaDLCMS
        
        and look at ``searchschema.py``.

        - Reformating the documentation to valid ReST.
        
        1.1.4
        -----
        
        Features added:
        
        - SilvaFind does not add a default search instance inside
        the service_find directory anymore. This was only being
        used by the dlcms, which will add it anyway, if it's not there.
        
        1.1.3 (2008/03/03)
        ------------------
        
        Changes:
        
        - SilvaFind is now using Silva 2.0 zcml extension
        registration.  From this version forward this
        product will not work in Silva 1.6 or lower.
        
        - Changed product to work with Silva 2.1
        zcml extension registration.
        
        Bugs Fixed:
        
        - metatypecriterion used all types when no selection was
        made in SMI, it should have used all *available* types
        instead since this could be overwritten with an adapter.
        
        1.1.2
        -----
        
        Changes:
        
        - i18n readied for Silva 2.0+.
        
        - Changed product to work with Silva 2.1
        zcml extension registration.
        
        1.1.1.2
        -------
        
        Changes:
        
        - metatypecriterion allows for list values.
        
        - Some code refactoring in MetatypeCriterionView, so it's easier
        to override.
        
        - Changed the line and border colors in the public view from green
        to gray and removed a green background so it's less likely that
        the SilvaFind colors will conflict with a user's site design.
        
        - Empty searches show nothing instead of everything.
        
        Bugs Fixed:
        
        - Removed hardcoded Silva Document checks in favor of IVersion
        interfaces.
        
        - KeyError for meta_type when doing empty searches.
        
        - SilvaFind search was searching on all "search content" fields,
        and ignoring the checkboxes.
        
        1.1.1
        -----
        
        Bugs Fixed:
        
        - Getting path criterion value from request failed because paths
        in the catalog can't have unicode characters.
