+= Nextcloud with OCR and Elasticsearch for Full-Text Searching
+
+To get elasticsearch to run, you'll need to run this on the host:
+sysctl -w vm.max_map_count=262144
+
+You can build and start all three containers (nextcloud, db and elasticsearch) with:
+
+$docker-compose up
+
+Go to:  http://[host]:9900/
+
+Make up user/pass, I uncheck installing the additional apps at the bottom
+
+Disable dashboard under user > settings
+
+== OCR
+1. go into settings > basic settings > set cron
+1. install apps (workflow ocr)
+1. create flow:
+    2. add new ocr flow
+    2. when: file created
+    2. file mime type > is > pdf document
+    2. (USE IS AND NOT MATCHES!!!)
+
+== Full text
+
+1. Install apps (full text, full text elastic, full text - files)
+1. To to Settings > Full Text Search
+1. Configure settings appropriately.  Address is:  http://user:pass@elasticsearch:9200/
+1. Now you have to run the fulltextsearch index manually one time
+    2. shell into container, enable www-data account (chsh)
+    2. go to /var/www/html and run: php occ fulltextsearch:index
+    2. disable www-data account (chsh back to nologin)
+
