Field types

Nixiesearch supports following field types:

• text fields: text, text[].
• numeric fields: int, float, long, double, bool, int[], long[], float[], double[].
• geolocation fields: geopoint
• date fields: date, datetime

Setting field type

In the field definition in the index mapping the required field type defines the underlying data type used to store and process the field.

For example, defining a text field looks like this:

schema:
  movies:
    fields:
      title:
        type: text # <-- the field type is here
        search: 
          semantic:
            model: e5-small

Field type should be defined in advance before you start indexing documents, as it affects:

• the way field is stored on disk (or not stored at all, if you set stored: false).
• underlying index structures if you plan to search, filter, facet and sort over this field.
• document schema check during ingestion.
