Can I find a specific year that exists in a date?

Question

Can we do a search for just the Year of birth in the Date of Birth attribute? If yes, would you please send a query of what that might look like?  Using the following API https://docs.reltio.com/entitiesapi/searchentity.html

Answer

The birthDate is defined as a Date.

  {
 "label": "Date of Birth",
 "name": "birthDate",
 "description": "Date of Birth",
 "type": "Date",
 "hidden": false,
 "important": false,
 "system": false,
 "required": false,
 "faceted": true,
 "searchable": true,
 "attributeOrdering": {
 "orderingStrategy": "LUD"
                    },
 "uri": "configuration/entityTypes/person/attributes/birthDate",
 "skipInDataAccess": false
                }

The safest and most efficient way to find all occurrences of the year 1980 would be to find all person entityType where the birthYear is 1980, you need to specify a time range filter from 1 Jan till 31 Dec 1980.

"filter": "(equals(type,'configuration/entityTypes/person') AND 
range(attributes.birthDate, '315532800000', '347068800000'))"

If an attribute is defined as a string, the following filter would work to find a specific selection.  For more information regarding filters please refer to this link.

"filter": "(equals(type,'configuration/entityTypes/person') AND 
startsWith(attributes.<attributedDefinedAsString>, '<a string constant>'))"
