在Restheart中查询文档（文本搜索）

Question

我创建了一个集合并在 mondo shell 中将该字段索引为 "text"。然后我使用以下参数查询文档：

localhost:8080/db/tags?filter={"$text":{"$search":"some text"}}

并得到错误：

http status code 500
http status description "Internal Server Error"
message "Query failed with error code 2 and error message 'Too many text expressions' on server 127.0.0.1:27017"

但是在mongoshell中一切正常。我对这个查询得到了正确的回应：

db.tags.find({"$text":{"$search":"some text"}})

怎么了？我通过这些教程完成了所有操作：

https://docs.mongodb.com/manual/reference/operator/query/text/#text-query-examples

Answer 1

我建议使用 RESTHeart 而不是 Mongo shell 重新创建索引。

首先，删除带有 shell 的索引，然后按照以下示例重新创建它：https://restheart.org/learn/indexes/

例如，您可以使用以下内容为集合 tags 创建命名索引：

PUT /db/tags/_indexes/<index_id> {"keys": {"title": "text" }}

HTTP/1.1 201 Created

那么请告诉我们它是否有效。

已更新:

下面是我在 RESTHeart 上成功测试全文搜索所做的工作（顺便说一句，我使用的是 httpie 客户端，但 curl 的工作方式类似）：

cd 进入 RESTHeart 文件夹
使用 docker-compose up

然后发出以下命令：

创建数据库

http -a admin:changeit PUT http://localhost:8080/mydb

创建一个集合

http -a admin:changeit PUT http://localhost:8080/mydb/sample

POST 示例文档

http -a admin:changeit POST http://localhost:8080/mydb/sample < sample.json

创建一个名为 "about" 的集合索引，它使用 JSON 文档中的 "about" 元素进行文本索引和搜索

http -j -a admin:changeit PUT http://localhost:8080/mydb/sample/_indexes/about keys:='{"about":"text"}}'

查看索引

http -a admin:changeit GET http://localhost:8080/mydb/sample/_indexes

执行成功的全文搜索

http -a admin:changeit GET http://localhost:8080/mydb/sample?filter='{"$text":{"$search":"\"Consequat fugiat commodo irure\""}}'

您将在附件中找到 sample.json.zip 文件。

我建议将上述步骤与您正在做的进行比较，看看是否存在显着差异。
