>Subject: [PATCH] Bug 37871: Remove extraneous 246 subfields from the title
> mappings (Elasticsearch, MARC21)
>
>This patch limits indexing of field 246 to $a, $b, $n, and $p in
>various title indexes.
>Previously, all 246 subfields were indexed, including non-title
>subfields such as $i (Display text), $g (Miscellaneous information),
>and linking subfields, making the title index very large and giving
>false results.
>
>To test:
>
>1. Add all the 246 subfields to the default bibliographic framework
>   1.1. Go to Administration > MARC bibliographic framework
>   1.2. Click Actions > MARC structure next to the Default framework
>   1.3. Search for 246
>   1.4. Click Actions > Edit subfields
>   1.5. For each subfield, make sure Editor is checked
>   1.6. Click Save changes
>
>2. Create a new record and fill out all the 246 subfields
>   2.1. Go to Cataloging
>   2.2. Click New record
>   2.3. Fill out the mandatory fields (000, 003, 005, 008, 040$c,
>        245$a, 942$c)
>   2.4. Fill out all the subfields in 246 (I simply write the name of
>        the subfield in the text field e.g. Display text in 246$i)
>   2.5. Click Save
>   2.6. Click Normal to access the detailed record
>
>3. View the Elastic search record
>   --> All the subfields (including "Display text", "Miscellaneous
>       information" and other non-title subfields) should be indexed in
>       - title
>       - title__suggestion
>       - title-abbreviated
>       - title-abbreviated__sort
>       - title expanded
>       - title-expanded__sort
>       - title-former
>       - title-former__sort
>
>4. Make a title or keyword search for "Display" (or whatever you wrote
>   in 246$i)
>   --> Your record should be in the results
>
>5. Apply patch
>
>6. Rebuild the index using -r
>
>koha-elasticsearch --rebuild -d -r -v kohadev
>
>7. Redo step 3
>   --> Only 246 $a, $b, $n, and $p should be indexed
>
>8. Redo step 4
>   --> Your record should NOT be in the results
