Full text search

Install following apps:

Full text search - Apps
Full text search - Elasticsearch Platform
Full text search - Files
Full text search - OCR

setup elasticsearch

copy default config

es_args=(--name nextcloud_elasticsearch --hostname elasticsearch --net nextcloud -e "discovery.type=single-node" -e  ES_JAVA_OPTS="-Xms6G -Xmx6G")

docker run --rm "${es_args[@]}" -dit elasticsearch:8.18.0 /bin/bash

docker cp nextcloud_elasticsearch:/usr/share/elasticsearch/config ./es/
docker cp nextcloud_elasticsearch:/usr/share/elasticsearch/data ./es/
docker cp nextcloud_elasticsearch:/usr/share/elasticsearch/plugins ./es/

docker stop nextcloud_elasticsearch

set volume bind args.

es_volume_args=(-v ./es/config:/usr/share/elasticsearch/config -v ./es/data:/usr/share/elasticsearch/data -v ./es/plugins:/usr/share/elasticsearch/plugins)

disable ssl

append following on es/config/elasticsearch.yml

xpack.security.enabled: false
xpack.security.http.ssl.enabled: false
xpack.security.transport.ssl.enabled: false

if you had forgotten to do above

Do this afterward:

docker run --rm "${es_args[@]}" "${es_volume_args[@]}" -it elasticsearch:8.18.0 /bin/bash

bin/elasticsearch-keystore remove xpack.security.transport.ssl.keystore.secure_password
bin/elasticsearch-keystore remove xpack.security.transport.ssl.truststore.secure_password
bin/elasticsearch-keystore remove xpack.security.http.ssl.keystore.secure_password

install plugins

docker run --rm "${es_args[@]}" "${es_volume_args[@]}" -it elasticsearch:8.18.0 /bin/bash

./bin/elasticsearch-plugin list
# check whether following plugins are already installed
./bin/elasticsearch-plugin install analysis-kuromoji
./bin/elasticsearch-plugin install analysis-icu
exit

start

# -p 9200:9200 -p 9300:9300 
docker run -d --rm "${es_args[@]}" "${es_volume_args[@]}" elasticsearch:8.18.0

check

check whether fts works

docker exec -it -u www-data nextcloud_main /bin/bash

# whole test and check connection
php ./occ fulltextsearch:test

# generate index
php ./occ fulltextsearch:index

fts daemon container

docker run --rm --name nextcloud_fts --network nextcloud -v ./nextcloud:/var/www/html -u www-data -d nextcloud /var/www/html/occ fulltextsearch:live

to stop daemon

docker exec -it -u www-data nextcloud_fts /var/www/html/occ fulltextsearch:stop

collabora office

To install additional fonts (for example Japanese fonts), we have to prepare out own collabora server. (And Japanese fonts are installed by default?)

note: With own collabora server, iOS app's viewer does not work. (but, with the embeded one, it works...) So I disabled collabora.

docker run --rm -d --network nextcloud -e "extra_params=--o:ssl.enable=false" --name nextcloud_collabora -p 9980:9980 collabora/code

Office - Administration settings - Nextcloud

Item	Value
Nextcloud Office / User your own server	Yes
URL (and Port) of Collabora Online-server	http://hoge:9980

note: The URL should be accessible from user's browser. The host machine's address would be good. Collabora container's address would not be accessible.
