materialize: Materialize Lazy Mappings

Description

Usage

materialize(corpus, range = seq_along(corpus))

Arguments

corpus

A document collection with lazy mappings.

range

The indices of documents to be materialized.

Value

• A corpus with materialized, i.e., all mappings computed and applied, documents for the requested range.
