Enable Lila search

• Install elasticsearch 7.x.x

  No special config is necessary. We'll use the default port 9200

• Setup lila-search:

  git clone https://github.com/lichess-org/lila-search
  cd lila-search
  sbt stage
  ./target/universal/stage/bin/lila-search
  

  sbt run does not work for lila-search at press time but you can use stage build. Maybe this will be fixed.

• Add the following line to lila/conf/application.conf:

  search.enabled = true
  

• Either use spamdb to add and automatically index games, posts, and teams:

  spamdb/spamdb.py --es   # --es makes spamdb connect to elasticsearch at localhost:9200 and index your database
  

• Or create indices manually (games will only be indexed on completion or computer analysis):

  • Before playing / analyzing any games on lila, you must do this:

    curl -XPOST http://localhost:9673/mapping/game
    

  • Now you can startup lila, login as the lichess user, go to http://localhost:9663/dev/cli, and run these commands:

    forum search reset
    team search reset
    study search reset
    

You should now be able to search.
