What field data types does Elasticsearch support?

Elasticsearch supports a rich set of field data types. String types: text (analyzed, for full-text search) and keyword (not analyzed, for exact match/aggregations). Numeric types: long, integer, short, byte, double, float. Date types: date (stores dates as milliseconds since epoch). Boolean: boolean. Geo types: geo_point (lat/lon) and geo_shape (complex geometries). Specialized types: ip (IPv4/IPv6 addresses with CIDR range query support), dense_vector (fixed-length float arrays for vector search / kNN), completion (for fast autocomplete suggestions), and binary (Base64-encoded binary data).
