As a user I would like to know why a search result matched

I'm particularly interested in this for the API - not so much the UI - in the project where I currently use CKAN.

Some ways of showing relevance:

• ordered by some notion of relevance
• which fields matched
• the text context

CKAN already does the first. Enabling highlighting in solr and adding that information to the package_search output would support the latter two.

This would be especially useful with https://github.com/stadt-karlsruhe/ckanext-extractor

I'm thinking of doing this in a plugin if we prioritise it in the next few sprints, but it would be nice as core functionality since it's not so nice to override package_search in a plugin.

I'm keen to hear your thoughts on this - if people have opinions on how it should be done, whether they've seen similar demand, etc.

I can imagine a button or checkbox that opens a box or pane that reveails the details on the fiels used, what matched, how it was scored.
