PLOS Search (research articles)

**Plugin functionality:** this plugin uses the query to find the top 5 related research articles from [PLOS Journals](http://plos.org/), the most influential nonprofit open access publisher. It lists the title, authors, journal and year of publication providing a direct link to content. The more_at link points to PLOS' search page with results for the same query.

**Plugin data source (API):** [PLOS Search API](http://api.plos.org/solr/faq/). It needs an API key to work.

**Example queries:** A simple example query is `plos dinosaurs` and the results are below, five scientific articles involving dinosaurs:

The API provides more complex queries, so you can search for papers about dinosaurs that have metabolism in the title: `plos dinosaurs title:metabolism`

**Plugin Audience:** mainly scientists, but since all articles are open access it is useful for everybody.

**Have you done any cross-browser testing?** No, just ran on Firefox 20.0 and Chromium 25.0.1364.160.

**Any issue you're having?** What should be the default behaviour if the query returns 0 articles? Should it show the zeroclickinfo box and report that it found no result or it should simply not appear?
