Hi,

Could someone help me on the below issue.

I have below field in my index,

> "postalcode" : 123 456

below mapping for the field,

> "postalCode": {  
> "type": "text",  
> "fields": {  
> "keyword": {  
> "type": "keyword",  
> "ignore\_above": 256  
> }  
> },  
> "analyzer": "ngram\_analyzer",  
> "search\_analyzer": "standard"  
> }

below settings for ngram\_analyzer

> "settings": {  
> "index": {  
> "number\_of\_shards": "5",  
> "analysis": {  
> "filter": {  
> "ngram\_filter": {  
> "type": "edge\_ngram",  
> "min\_gram": "2",  
> "max\_gram": "20"  
> },  
> "ascii\_filter": {  
> "type": "asciifolding",  
> "preserve\_original" : true  
> }  
> },  
> "analyzer": {  
> "ngram\_analyzer": {  
> "filter": [  
> "lowercase",  
> "ngram\_filter",  
> "ascii\_filter"  
> ],  
> "type": "custom",  
> "tokenizer": "standard"  
> }  
> }  
> },  
> "number\_of\_replicas": "2"  
> }  
> }

below are my different search scenarios of postalCode field,

1. postalCode: 12
2. postalCode: 123456
3. postalCode: 123 456

Please help me on how to get the document for these different search query scenarios.  
All the three search scenarios should return the document which  
contains postalCode : 123 456 value

Thanks,  
Ram Prasad G
