//! Shared full-text extraction: concatenate a document's string field values
//! into the single text blob the inverted index analyzes.

/// Concatenate all top-level string-valued fields of a document object into
/// the text the full-text inverted index indexes.
///
/// Used by the forward PUT indexing path AND by DELETE-rollback re-indexing so
/// both produce byte-identical text (and therefore identical postings, since
/// `nodedb_fts::analyze` is deterministic). Non-object values and non-string
/// fields contribute nothing.
