Question

从这个page，我正在尝试这个：

[15] pry(main)> puts Post.search("price:>600").size
  Post Search (18.7ms)  curl http://localhost:9200/posts_development/_search?pretty -d '{"query":{"dis_max":{"queries":[{"match":{"_all":{"query":"price:\u003e600","operator":"and","boost":10,"analyzer":"searchkick_search"}}},{"match":{"_all":{"query":"price:\u003e600","operator":"and","boost":10,"analyzer":"searchkick_search2"}}},{"match":{"_all":{"query":"price:\u003e600","operator":"and","boost":1,"fuzziness":1,"max_expansions":3,"analyzer":"searchkick_search"}}},{"match":{"_all":{"query":"price:\u003e600","operator":"and","boost":1,"fuzziness":1,"max_expansions":3,"analyzer":"searchkick_search2"}}}]}},"size":100000,"from":0,"fields":[]}'
0
=> nil

虽然我确实有价格大于 600 的条目：

[16] pry(main)> puts Post.where("price>600").size
   (0.2ms)  SELECT COUNT(*) FROM "posts" WHERE (price>600)
45
=> nil

为什么这两个有不同的输出有什么建议吗？可能是转义字符 "query":"price:\u003e600"?

我也试过：

[37] pry(main)> Post.search(where: {price: {gt: 600}}).size
  Post Search (9.8ms)  curl http://localhost:9200/posts_development/_search?pretty -d '{"query":{"match_all":{}},"size":100000,"from":0,"filter":{"and":[{"range":{"price":{"from":600,"include_lower":true}}}]},"fields":[]}'
  Post Load (0.5ms)  SELECT "posts".* FROM "posts" WHERE "posts"."id" IN (4, 9, 11, 16, 28, 35, 42, 5, 12, 17, 24, 29, 31, 36, 43, 48, 50, 1, 6, 13, 20, 25, 32, 37, 44, 2, 7, 14, 19, 21, 26, 33, 38, 40, 45, 3, 8, 10, 15, 22, 27, 34, 39, 41, 46)
=> 45

[38] pry(main)> Post.search(facets: {price: {ranges: [{from: 600}] }  }).size
  Post Search (10.4ms)  curl http://localhost:9200/posts_development/_search?pretty -d '{"query":{"match_all":{}},"size":100000,"from":0,"facets":{"price":{"range":{"price":[{"from":600}]}}},"fields":[]}'
  Post Load (0.7ms)  SELECT "posts".* FROM "posts" WHERE "posts"."id" IN (4, 9, 11, 16, 23, 28, 30, 35, 42, 47, 5, 12, 17, 24, 29, 31, 36, 43, 48, 50, 1, 6, 13, 18, 20, 25, 32, 37, 44, 49, 2, 7, 14, 19, 21, 26, 33, 38, 40, 45, 3, 8, 10, 15, 22, 27, 34, 39, 41, 46)
=> 50

where 达到了我的预期：45 个帖子。但是我不明白facet，谁能帮我解决这个问题？

想通了：

[42] pry(main)> Post.search(query: {query_string: {query: 'price:>600'}}).size
  Post Search (8.8ms)  curl http://localhost:9200/posts_development/_search?pretty -d '{"query":{"query_string":{"query":"price:\u003e600"}},"size":100000,"from":0,"fields":[]}'
  Post Load (0.5ms)  SELECT "posts".* FROM "posts" WHERE "posts"."id" IN (4, 9, 11, 16, 28, 35, 42, 5, 12, 17, 24, 29, 31, 36, 43, 48, 50, 1, 6, 13, 20, 25, 32, 37, 44, 2, 7, 14, 19, 21, 26, 33, 38, 40, 45, 3, 8, 10, 15, 22, 27, 34, 39, 41, 46)
=> 45

虽然我还没看懂facet
