it's can get when i search use es match query.the match query is like

```auto
 {"query": 
    {
        "bool": {
       "must": [
          {
             "match": {
             "message": "too long"}
          }],
         "must_not": [],
     "should": []}},
     "from": 0,
     "size": 10,
     "sort": [],
     "aggs": { }
}

```

but i can't get when i use luence query like "\_search?q=message:"too long"&size=1000".

The content of "message" is "java.util.concurrent.TimeoutException: Remote system has been silent for too long. (more than 48.0 hours)".

but it's all can get when i search info "Remote system".

</div>

Works for me here when I use the default mapping:

```
DELETE test
POST test/_doc/1
{
 "message": "java.util.concurrent.TimeoutException: Remote system has been silent for too long. (more than 48.0 hours)"
}
GET test/_search?q=message:"too long"&size=1000

```

This matches the doc, as does the longer `match` query example you shared.  
This is probably down to your mapping. Can you share your mapping configuration?

thanks for you answer。  
my mapping is

Thanks. You're using an analyzer called `ik_max_word` which I can't see and will be defined in your settings.  
One of the ways of debugging this and other issues yourself is to use the [\_analyze](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-analyze.html) api to see how the document and query is tokenized and the [\_explain](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-explain.html) API to show how a query does (or doesn't) match a doc.

</div>

I try it,  
The analyze is

```auto
{
    "tokens": [
        {
            "token": "too",
            "start_offset": 0,
            "end_offset": 3,
            "type": "ENGLISH",
            "position": 0
        },
        {
            "token": "long",
            "start_offset": 4,
            "end_offset": 8,
            "type": "ENGLISH",
            "position": 1
        }
    ]
}

```

the explain is

```auto
{
    "_index": "test",
    "_type": "_doc",
    "_id": "xHPL8nUBlF-KtMFxz-1J",
    "matched": false,
    "explanation": {
        "value": 0.0,
        "description": "Failure to meet condition(s) of required/prohibited clause(s)",
        "details": [
            {
                "value": 0.0,
                "description": "no match on required clause (message:\"too long\")",
                "details": [
                    {
                        "value": 0.0,
                        "description": "no matching phrase",
                        "details": []
                    }
                ]
            },
            {
                "value": 0.0,
                "description": "no match on required clause (MatchNoDocsQuery(\"Type list does not contain the index type\"))",
                "details": [
                    {
                        "value": 0.0,
                        "description": "MatchNoDocsQuery(\"Type list does not contain the index type\") doesn't match id 0",
                        "details": []
                    }
                ]
            }
        ]
    }
}

```

it's amazing that The content has “too long ” phrase.

It looks like your mapping declares a document type `doc` but your query url references the type `_doc`

Sorry, the "\_doc" is error. my type is "test",the data is like this:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/b/3/b35367340f7307b41dbed90afc84acc65fd4d54f.png)

I try request again, like this:

```auto
http://sloth0.dg.163.org:9201/test/test/xHPL8nUBlF-KtMFxz-1J/_explain?q=message:"too long"

```

The result is:

```auto

    "_index": "test",
    "_type": "test",
    "_id": "xHPL8nUBlF-KtMFxz-1J",
    "matched": false,
    "explanation": {
        "value": 0.0,
        "description": "no matching phrase",
        "details": []
    }
}

```

I also can't get more information

My output from the analyze API is identical to yours and yet the query below works OK in 6.6. and 7.10.  
Can you try run this and compare? Then try it using your Analyzer..

```
DELETE test
POST test/_doc/1
{
 "message": "java.util.concurrent.TimeoutException: Remote system has been silent for too long. (more than 48.0 hours)"
}
GET test/_analyze
{
  "field": "message", 
  "text": "too long"
}
GET test/_doc/1/_explain?q=message:"too long"
```

Did my example (with the default analyzer) work?  
What is the output of the analyze api using your analyzer and the string that is your document’s message?
