Class TextFieldArgs<K>

java.lang.Object

io.lettuce.core.search.arguments.FieldArgs<K>

io.lettuce.core.search.arguments.TextFieldArgs<K>

Type Parameters:

K - Key type

public class TextFieldArgs<K>
extends FieldArgs<K>

Field arguments for TEXT fields in a RediSearch index.

Text fields are specifically designed for storing human language text. When indexing text fields, Redis performs several transformations to optimize search capabilities. The text is transformed to lowercase, allowing case-insensitive searches. The data is tokenized, meaning it is split into individual words or tokens, which enables efficient full-text search functionality.
