添加 postgresql 中文全文搜索 zhparser/jieba/pgroonga

[davidlauhn]

postgresql自带的搜索不支持中文，导致ttrss搜索中文的根本没法用，不知道有没有计划添加 zhparser/jieba/pgrooga之类的？

[HenryQW]

没有这个计划，看起来需要更改 TTRSS 的搜索逻辑，mysql 有这个问题吗？

[HenryQW]

推荐通过阅读器来实现全文搜索，比如 Reeder

[davidlauhn]

mysql没有试过哦，我自己慢慢试试看，谢谢

如果没有理解错其实tinytinyrss已经支持，只要配置好pgrooga就能设置全局搜索的默认语言了？

太菜，搞不懂pgrooga怎么配置，然后用zhparser实现了

[HenryQW]

@davidlauhn 可以分享一下解决方案，我看看能不能加进去。或者直接 PR 就完美了！

[HenryQW]

@jostyee 没看懂 DEFAULT_SEARCH_LANGUAGE 的用法，我试了下那个贴里的办法还是不行。

@HenryQW 本人非码农/非运维，以下全部基于copy/paste，只知然，不知所以然，而且不一定准确，没法接受提问，因为真的不懂，抱歉 :-)

修改了两个 docker image

docker-compose.yml

services:
  database.postgres:
    image: davidlauhn/postgres-11-with-zhparser:latest
    container_name: postgres
    environment:
      - PG_PASSWORD=password # please change the password
      - DB_EXTENSION=pg_trgm
    volumes:
      - ~/postgres/data/:/var/lib/postgresql/ # persist postgres data to ~/postgres/data/ on the host
    restart: always

  service.rss:
    image: davidlauhn/awesome-ttrss:latest
    container_name: ttrss
    ports:
      - 80:80
    environment:
      - SELF_URL_PATH=http://domain.name/ # please change to your own domain
      - DB_HOST=database.postgres
      - DB_PORT=5432
      - DB_NAME=ttrss
      - DB_USER=postgres
      - DB_PASS=password # please change the password
      - ENABLE_PLUGINS=auth_internal, fever # auth_internal is required. Plugins enabled here will be enabled for all users as system plugins
    stdin_open: true
    tty: true
    restart: always
    command: sh -c 'sh /wait-for.sh database.postgres:5432 -- php /configure-db.php && exec s6-svscan /etc/s6/'

  service.mercury: # set Mercury Parser API endpoint to `service.mercury:3000` on TTRSS plugin setting page
    image: wangqiru/mercury-parser-api:latest
    container_name: mercury
    expose:
      - 3000
    restart: always

    service.opencc: # set OpenCC API endpoint to `service.opencc:3000` on TTRSS plugin setting page
    image: wangqiru/opencc-api-server:latest
    container_name: opencc
    environment:
      NODE_ENV: production
    expose:
      - 3000
    restart: always

然后配置一下zhparser

    docker exec -it postgres /bin/sh
    psql -U postgres -d ttrss -c 'CREATE EXTENSION zhparser'
    psql ttrss postgres -c 'CREATE TEXT SEARCH CONFIGURATION Chinese (PARSER = zhparser)'
    psql ttrss postgres -c 'ALTER TEXT SEARCH CONFIGURATION Chinese ADD MAPPING FOR n,v,a,i,e,l WITH simple'
    psql ttrss postgres
    update ttrss_entries set tsvector_combined = to_tsvector('Chinese', content);

重启一下postgresql，更改ttrss的搜索语言为Chinese即可。

中文搜索堪用，但貌似分词稍微有点点小问题，zhparser会把长词拆成短词匹配，应该是zhparser默认的配置还需要调教，因我要求也不高，所以将就着用了

[jostyee]

@davidlauhn 启用zhparser没那么麻烦，sameersbn/postgresql 支持通过env开启的：

https://github.com/sameersbn/docker-postgresql#enabling-extensions

[davidlauhn]

@jostyee 我也不想这么大费周章，可不懂嘛，所以就跟着说明一步步走咯 :-)

[HenryQW]

@jostyee zhparser 还需要装依赖的，不能直接开启

有空调查一下可行性。欢迎大佬 PR！

[hoilc]

简单地改了版，有兴趣的可以试用下

postgres镜像 hoilc/postgres-chinese-textsearch:latest

ttrss镜像 hoilc/ttrss:latest, 需要添加环境变量TEXTSEARCH_EXTENSION=pg_jieba,zhparser

https://github.com/hoilc/Awesome-TTRSS/blob/master/docker-compose.yml

@HenryQW 这个好用的话可以合并过来，ttrss的中文搜索的确不行

[HenryQW]

PR 一下嘛？我最近太忙了

[ptsa]

@hoilc 提交下pr
@HenryQW 他这个postgresql 也有改 你要fork 下他的postgresql 吧 https://github.com/hoilc/postgres-chinese-textsearch

[ptsa]

@hoilc 没有提交pr 我复制了他的代码 提交了 pr

[0rt]

请问这个修改汇到latest没有？我尝试搜索中文还是没成功

[ptsa]

@0rt 我提交没成功。可能方法没对
