When working with hierarchical subject headings, it is sometimes helpful
to do a search for all records with a specific subject, plus
broader/narrower/related subjects. This patch adds a suggestion plugin for
these "exploded" subject searches to Koha. Note that this patch depends on
both bug 8211 AND bug 8209.
To test (NOTE: this test plan covers both 8211 and 8726):
1) Make sure you have a bunch of hierarchical subjects. I created
geographical subjects for "Arizona," "United States," and "Phoenix,"
and linked them together using 551s, and made sure I had a half
dozen records linking to each (but not all to all three).
2) Do a search for su-br:Arizona (or choose "Subject and broader terms"
on the advanced search screen with "more options" displayed), and
check that you get the records with the subject "Arizona" and the
records with the subject "United States"
3) Do a search for su-na:Arizona (or choose "Subject and narrower terms"
on the advanced search screen with "more options" displayed), and
check that you get the records with the subject "Arizona" and the
records with the subject "Phoenix"
4) Do a search for su-rl:Arizona (or choose "Subject and related terms"
on the advanced search screen with "more options" displayed), and
check that you get the records with the subject "Arizona," the
records with the subject "United States," and the records with the
subject "Phoenix"
5) Ensure that other searches still work (keyword, subject, ccl,
whatever)
6) Use "Did you mean?" page in admin section to enable ExplodedTerms
plugin
7) Do a keyword search on the OPAC, confirm that searching for exploded
terms is suggested.
8) Do a subject search on the OPAC, confirm that searching for exploded
terms is suggested.
9) Do a non-keyword, non-subject search on the OPAC, confirm that
searching for exploded terms is NOT suggested.
10) Disable ExplodedTerms plugin and enable AuthorityFile plugin.
11) Do search on OPAC, confirm suggestions are made from authority file.
12) Sign off

Split into two patches. This patch includes only the functionality.
One of the ideas behind authority records is that users who search for
one term should have related terms (according to the authority file)
suggested to them. At the moment, Koha doesn't do that. Adding an
authority searching step to regular searches and displaying any
suggestions in a "Did you mean" bar at the top of the results would be
very useful.
This commit adds a Koha::SuggestionEngine class which is in charge of
getting suggestions from individual suggestion engine plugins, which
much be in the Koha::SuggestionEngine::Plugin::* namespace, and extend
Koha::SuggestionEngine::Base. Suggestions are loaded asynchronously
using AJAX, and a link to a page with suggestions is provided for users
with Javascript turned off.
The AuthorityFile suggestion engine plugin looks up the specified search
terms in the authority file and then suggests searches for records using
matching authorities.

Test plan:
- Verified database update added system preference correctly,
pref defaults to OFF
- Verified search results and detail pages in OPAC and staff
still worked the same as before
* for no results
* with results
- Activated system preference and tested various searches
* Searches from simple search
* Searches from advanced search
* Search links in records
- Deactivated Javascript - verified fallback works correctly
Notes:
- Suggested terms can include autorities with no linked records.
- When combining more than one search option using advanced search
this results in "no suggestions" more often. Feature works best
from simple search.
Overall great feature making use of authorities in a user friendly way!
