"grade": 8,
"exams": [

"subject": "Maths",

"marks" : 90},
{

]
}'
In this example, we simply named the field paths (such as /exams/test). Solr will automatically attempt to add
the content of the field from the JSON input to the index in a field with the same name.
Note that if you are not working in Schemaless Mode, where fields that don't exist will be created on the
fly with Solr's best guess for the field type, documents may get rejected if the fields do not exist in the
schema before indexing.
Wildcards
Instead of specifying all the field names explicitly, it is possible to specify wildcards to map fields automatically.
There are two restrictions: wildcards can only be used at the end of the json-path, and the split path cannot
use wildcards. A single asterisk "*" maps only to direct children, and a double asterisk "**" maps recursively to all
descendants. The following are example wildcard path mappings:
f=$FQN:/**: maps all fields to the fully qualified name ( $FQN) of the JSON field. The fully qualified
name is obtained by concatenating all the keys in the hierarchy with a period (.) as a delimiter. This is
the default behavior if no f path mappings are specified.
f=/docs/*: maps all the fields under docs and in the name as given in json
f=/docs/**: maps all the fields under docs and its children in the name as given in json
f=searchField:/docs/*: maps all fields under /docs to a single field called ‘searchField’
f=searchField:/docs/**: maps all fields under /docs and its children to searchField
With wildcards we can further simplify our previous example as follows:
