使用PHP的MongoDB全文搜索 [英] MongoDB full text search using PHP

问题描述

似乎，我对如何执行此操作的搜索会带回一年的结果，并且显然不再起作用，或者我做的事情不正确.

It seems that my searching for how to do this brings back results that are a year old and apparently no longer work or I am not doing something correctly.

通过MongoDB命令行，我已经运行了该工具以建立索引:

Through the MongoDB command line, I have run this for indexing:

db.collectiontest.ensureIndex({"$ **":文本"}，{名称:"TextIndex"})

db.collectiontest.ensureIndex( { "$**": "text" }, { name: "TextIndex" } )

基于以下示例进行了

http://docs.mongodb. org/manual/tutorial/create-text-index-on-multiple-fields/

执行该错误后，我没有收到错误消息.

I do not receive an error when that is executed.

以下是我尝试过的2个Stackoverflow帖子:

Here are 2 of the Stackoverflow postings I have tried:

如何使用php在全文索引中进行搜索mongodb

来自PHP的MongoDB集合runCommand

最后一篇文章，我尝试了接受的答案，但确保索引除外，因为我通过命令行和发布者的解决方案进行了此操作.两种方法都返回一条消息，显示"Array([errmsg] => no such cmd:text [bad cmd] =>".

The last post, I tried the accepted answer except the ensure index since I did that via command line and the poster's solution as well. Both methods returns a message showing "Array ( [errmsg] => no such cmd: text [bad cmd] =>" .

我正在运行具有最新版本的PHP和MongoDB的Ubuntu Server 12虚拟机.

I'm running a vm of Ubuntu Server 12 with latest release versions of PHP and MongoDB.

谢谢

推荐答案

如果您使用的是最新版本的mongodb，则正确的语法是

If you are using the latest version of mongodb, the correct syntax is

db.collection.ensureIndex(
                           {
                             subject: "text",
                             content: "text"
                           }
                         )

用于为单个集合中的多个文本字段建立索引，并且

for indexing multiple text fields in a single collection, and

 db.collection.ensureIndex(
                               {
                                 content: "text"
                               }
                             )

(用于单个字段).尝试修改您的sureIndex()调用以匹配上述模式之一，然后查看是否适合您.

for a single field. Try modifying your ensureIndex() call to match one of the above patterns and see if that works for you.

可以在此处找到正确的查询语法: http://docs. mongodb.org/manual/reference/operator/query/text/

The correct query syntax can be found here: http://docs.mongodb.org/manual/reference/operator/query/text/

db.articles.find( { $text: { $search: "coffee" } } )
