I have these symbols ![CF7CB807](https://us1.discourse-cdn.com/elastic/original/3X/d/5/d518c9dac98014ee179ca3b1b0c8c32005f877e1.png)

we have successfully persisted data for those but we we're having problems when retrieving those data for both nested and not nested fields. and also with wildcard

Can you guys help me how can I construct correct elasticsearch query with this.

unable to retrieve data example  
(not nested) value = \* sample#test#data \*  
(not nested) = sample#test#data  
(nested) = sample#test#data  
(nested) = \* sample#test#data \*

Mapping:  
"normalizer": {  
"testnormalizer": {  
"type": "custom",  
"char\_filter": ,  
"filter": [  
"lowercase",  
"asciifolding"  
]  
}  
}

Nested fields mapping:  
"nestedflds": {  
"type": "nested",  
"properties": {  
"attributeName": {  
"type": "keyword",  
"normalizer": "testnormalizer"  
},  
"attributeValue": {  
"type": "text",  
"fields": {  
"keyword": {  
"type": "keyword"  
}  
},  
"fielddata": true  
}  
}  
}

Not nested mapping:  
"testId": {  
"type": "keyword",  
"normalizer": "testnormalizer"  
},
