## Description

Use when extracting keywords (YAKE/RAKE) from documents, and, secondarily, when detecting document language or generating embeddings for RAG and search. Covers the keyword config (and its feature gating), `--detect-language`, and the standalone `embed` command with real flags.

# Extracting keywords, language, and embeddings

Use this for the enrichment surface around extraction: statistical keyword
extraction, language detection, and vector embeddings. Keywords and
language detection ride along with extraction and land on the result;
embeddings are produced by a dedicated `embed` command.

## Keywords (YAKE / RAKE)

Keyword extraction is configured via the `[keywords]` config block (or
inline JSON), there is no single `--keywords` CLI flag. When enabled,
extracted keywords appear on `result.extracted_keywords` (`extractedKeywords`
in Node.js; the CLI JSON field is `extracted_keywords`). Two algorithms are
available:

- **YAKE** (`"yake"`), statistical, unsupervised single-document
  extraction. Good general default.
- **RAKE** (`"rake"`), co-occurrence / phrase-based. Favors multi-word
  key phrases.

> Feature-gated: keyword extraction requires the CLI to be built with the
> `keywords-yake` and/or `keywords-rake` Cargo features (both are in the
> default/`full` build). If the CLI was built without them, the `[keywords]`
> config block is silently ignored, `result.extracted_keywords` simply stays empty
> rather than erroring. The `"yake"` algorithm needs `keywords-yake`; `"rake"`
> needs `keywords-rake`.

Enable via inline JSON on the CLI:

```bash
xberg extract paper.pdf --format json \
  --config-json '{"keywords":{"algorithm":"yake","max_keywords":15,"language":"en"}}' \
  | jq '.result.extracted_keywords'
```

Or in a config file:
