Hi,  
I have one field which is dateofbirth whose mapping is something like below  
"dateofbirth" : {  
"type" : "date",  
"fields" : {  
"tokens" : {  
"type" : "text"  
}  
},  
"ignore\_malformed" : true,  
"format" : "yyyy-MM-dd"  
},  
I have a use case where i need to search on the basis of yyyydd & yyyy & yyyyMM, Does any one know how to apply analyzer in such case, so that tokens can be created for searching.

A date gets converted to the milliseconds since the epoch (midnight in 1970) and a query will be a range query. You can specify the format when querying, that should just include the year or month. See [https://www.elastic.co/guide/en/elasticsearch/reference/7.4/query-dsl-range-query.html#range-query-field-params](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/query-dsl-range-query.html#range-query-field-params)
