This is an interface for quick and efficient browsing through records.
It presents a page at /cgi-bin/koha/opac-browse.pl that allows you to
enter the prefix of an author, title, or subject and it'll give you a
list of the options that match that. You can then scroll through these
and select the one you're after. Selecting it provides a list of records
that match that particular search.
To Test:
1 - Apply patches
2 - Update database (updatedatabase on kohadevbox)
3 - Compile the CSS
https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_client
yarn build --view=opac on kohadevbox
4 - Enable the new syspref OpacBrowseSearch
5 - Have ES running and some records in it
SearchEngine syspref set to Elasticsearch
6 - Browse to opac home, click 'Browse search' link
for your site)
7 - Test searching for author, title, and subject
8 - Verify that results are returned in expected order
9 - Experiment with fuzziness
https://www.elastic.co/guide/en/elasticsearch/reference/5.6/common-options.html#fuzziness
Options are: exact (0 edits), fuzzy (1 edit), very fuzzy (2 edits)
10 - Click any result and verify specific titles are correct
11 - Click through title to record and verify it is the correct record
12 - Test that disabling pref removes the link on the opac home

As of bug 20589 we no longer analyze sort fields and so we no longer need to append ".phrase"
to our sort in searches.
Additionally, sort fields based on 'sum' should also use sum in building the value to sort on
To test:
0 - Be using ES
1 - Find the most circulated item in your collection
2 - Search for '*'
3 - Sort by popularity DESC
4 - Note that item is not first
5 - Try to sort by anything but relevancy, it fails
6 - Apply patch
7 - Redo searches and sorts
8 - Things should now work as expected

Generate a list of fields for the query_string query fields parameter,
with possible boosts, instead of using "_all"-field. Also add "search"
flag in search_marc_to_field table so that certain mappings can be
excluded from searches. Add option to include/exclude fields in
query_string "fields" parameter depending on searching in OPAC or staff
client. Refactor code to remove all other dependencies on "_all"-field.
How to test:
1) Reindex authorities and biblios.
2) Search biblios and try to verify that this works as expected.
3) Search authorities and try to verify that this works as expected.
4) Go to "Search engine configuration"
5) Change some "Boost", "Staff client", and "OPAC" settings and save.
6) Verify that those settings where saved accordingly.
7) Click the "Biblios" or "Authorities" tab and change one or more
"Searchable" settings
8) Verfiy that those settings where saved accordingly.
9) Try to verify that these settings has taken effect by peforming
some biblios and/or authorities searches.

Adds preference ElasticsearchMARCFormat that controls whether MARC records are stored as ISO2709/MARCXML or array. Array is searchable by field and also indexes all subfields in the _all field for searching.
Test plan:
1. Test that searching and indexing works with the patch without any changes.
2. Switch to array format and index some records.
3. Check e.g. the 008 field of a record and verify that the record can be found with the contents enclosed in quotes.
4. Check that it's possible to search for a specific field/subfield. Search query: marc_data_array.fields.655.subfields.a:Diaries
5. Check that tests still pass, especially t/Koha/SearchEngine/Elasticsearch.t

Implement optimized indexing for Elasticsearch
How to test:
1) Time a full elasticsearch re-index without this patch by running the
rebuild_elastic_search.pl with the -d flag:
`koha-shell <instance_name> -c "time rebuild_elastic_search.pl -d"`.
2) Apply this patch.
3) Time a full re-index again, it should be about twice at fast (for a
couple of thousand biblios, with fewer biblios results may be more
unpredictable).

To test:
1 - Do some authority searches in Zebra
2 - Switch to ES and repeat, results will vary and some may fail
3 - Apply patch and dependencies
4 - Reindex ES
5 - Repeat searches, they should suceed and results should be similar to
Zebra
6 - Slight differences are okay, but results should (mostly) meet
expectations
A few notes:
We add a 'normalizer' to ensure we get a single token from the heading
indexes, this makes 'starts with' work as expcted
We switch to 'AND' for fields searched from cataloging editor - this
matches Zebra results
We force the '__sort' fields for sorting - if sorting looks wrong try
reducing the heading field to a single subfield - this will need to be
addressed on a future bug (multiple subfields create an array, ES sorts
those randomly)

Improvements:
1) Index settings moved from code to etc/searchengine/elasticsearch/index_config.yaml. An alternative can be specified in koha-conf.xml.
2) Field settings moved from code to etc/searchengine/elasticsearch/field_config.yaml. An alternative can be specified in koha-conf.xml.
3) mappings.yaml has been moved from admin/searchengine/elasticsearch to etc/searchengine/elasticsearch. An alternative can be specified in koha-conf.xml.
4) Default settings have been improved to remove punctuation from phrases used for sorting etc.
5) State variables are used for storing configuration to avoid parsing it multiple times.
6) A possibility to reset the fields too has been added to the reset operation of mappings administration.
7) mappings.yaml has been moved from admin/searchengine/elasticsearch to etc/searchengine/elasticsearch.
8) An stdno field type has been added for standard identifiers.
To test:
1) Run tests in t/Koha/SearchEngine/Elasticsearch.t
2) Clear tables search_fields and search_marc_map
3) Go to admin/searchengine/elasticsearch/mappings.pl?op=reset&i_know_what_i_am_doing=1
4) Verify that admin/searchengine/elasticsearch/mappings.pl displays the mappings properly, including ISBN and other standard number fields.
5) Index some records using the -d parameter with misc/search_tools/rebuild_elastic_search.pl to recreate the index
6) Verify that you can find the records
7) Put <elasticsearch_index_mappings>non_existent</elasticsearch_index_mappings> to koha-conf.xml
8) Verify that admin/searchengine/elasticsearch/mappings.pl?op=reset&i_know_what_i_am_doing=1 fails because it can't find non_existent.
9) Copy etc/searchengine/elasticsearch/mappings.yaml to a new location and make elasticsearch_index_mappings setting in koha-conf.xml point to it.
10) Make a change in the new mappings.yaml.
11) Clear table search_fields (mappings reset doesn't do it yet, see bug 20248)
12) Go to admin/searchengine/elasticsearch/mappings.pl?op=reset&i_know_what_i_am_doing=1
13) Verify that the changes you made are now visible in the mappings UI
