Creates a new 'Users' field in the search filters form. This field
requires new JavaScript and, to implement this, a new AJAX-callable
web service to search for users by name, with detailed restrictions
based on the current user's access to view profiles.
Implements a mechanism by which search engines can provide different
result orderings, and implements a 'by location' ordering within the
Solr search engine (available whenever the user starts their search
from within a course or activity).
Adds a new 'Gradual reindex' link to the search areas page for each
area. When clicked, this takes you to a confirm prompt, and then
adds each context from that search area to the indexing queue.
The search areas page now displays the 'Additional indexing queue'
(if it is non-empty). The table shows the first 10 items in the
queue, and it also indicates the total number in case there are
more. (I don't think people really need to see the entire
contents of it, so I didn't implement paging.)
Ensures that Solr will return available results, even if there are many
misses when using check_access(), by asking Solr for more results if the
counter says there should be more.
Improves performance by ending processing as soon as the requested page
of results is processed. Remaining number of pages is an "estimate"
based on the total result count from Solr and how many items we have
rejected up to this point.
Introducing both APIs in moodle along with:
- search_box widget to add a tiny search box
- admin settings with setup steps helper
- cache for search results
- template for a search result
- php unit stuff
Many thanks to Tomasz Muras, Prateek Sachan and Daniel Neis for their contributions, for starting this development
and for pushing for it to be completed. Also thanks to other contributors: Jonathan Harker and eugeneventer.
