New search implementation

[juliaflanders]

Create search and filter page

The search and filter page is a space where the user can execute searches and can filter the found set of articles.

Desirable features (still in draft):

• "generous interface": display the full set of articles with the ability to sort on various metadata fields
• user can see the full list of articles at the outset (rather than having to do a search first)
• sidebar displays a list of filters/facets that each indicate how many items there are that meet that criterion
• clicking on a facet limits the displayed set to items that contain that facet

Indexing

The index should include the following:

• Author
• Title
• Language
• Publication date
• DHQ keywords
• Author keywords
• Full text

Eventually, cited items should also be searchable/browsable once Biblio is fully integrated into the journal interface.
