i got stuck when searching with nGram filter

here is my index config  
\*  
localhost:9200/area\*

{

> "name": "translations",  
> "number\_of\_shards": 5,  
> "number\_of\_replicas": 0,  
> "analysis": {  
> "analyzer": {  
> "translation\_index\_analyzer": {  
> "type": "custom",  
> "tokenizer": "standard",  
> "filter": "standard,lowercase,translation,asciifolding"  
> },  
> "translation\_search\_analyzer": {  
> "type": "custom",  
> "tokenizer": "standard",  
> "filter": "standard,lowercase,asciifolding"  
> }  
> },  
> "filter": {  
> "translation": {  
> "type": "nGram",  
> "min\_gram": "2",  
> "max\_gram": "15"  
> }  
> }  
> }

and my mapping

- \*_localhost:9200/area/detail_

{

query\_string takes what you enter and interprets not as a phrase, but as  
individual parts of a Lucene query expression.  
Therefore [ho] and [rua] and [con] are interpreted as separate terms  
instead of a phrase.

query: { \<--- the outer query that you are building

bool: { \<-- the query used to put together everything you add with the [+] button.

```
  must: [ <-- your defined use of must to combine this expression in the overall boolean query

    { "bool" : { <-- my expansion of the query_string

      "should": [ <-- default for Lucene queries

          {term: { "testarea_name":"ho"}, <-- your terms in the "generated" query
          {term: { "testarea_name":"rua"},
          {term: { "testarea_name":"con"}

      ]
    }
  ]
}

```

}

I've shown it in ES format, even though it is never an ES query. It goes  
directly to Lucene.  
In Lucene

[ho rua con] becomes [testarea\_name:ho testarea\_name:rua testarea\_name:con]

I am using square brackets to delineate queries, because I find it confusing  
to use quotes, because quotes are special syntax in Lucene queries.

If you want a phrase, use quotes ["ho rua con"]. In the search box you  
enter actual quotes.  
You can then add slop (total extra words allowed) and even boost after  
the quotes.
