/** |
| 3 |
* Pinecone document index adapter (plan 362c31). |
| 4 |
* |
| 5 |
* A Pinecone "document index" is a schema-based index (API version 2026-07) |
| 6 |
* whose string fields can carry a BM25 full-text index. MxChat offers it as a |
| 7 |
* second, OPT-IN index type beside the classic vector index: same API key, |
| 8 |
* host and namespace fields, an "Index type" choice on the Pinecone card, and |
| 9 |
* a copy-migration that moves an existing classic index across with zero |
| 10 |
* embedding calls (the classic index already holds the chunk text in metadata |
| 11 |
* and the vector in values). |
| 12 |
* |
| 13 |
* Everything the plugin does against a document index goes through this class: |
| 14 |
* the data plane (documents/upsert, /search, /fetch, /list, /delete), the |
| 15 |
* control plane (create / describe / delete index) and the migration. The |
| 16 |
* classic vector code paths are NOT modified — each of them carries a one-line |
| 17 |
* guard that hands a document-index configuration to the matching method here, |
| 18 |
* so a site on the classic index runs exactly the code it ran before. |
| 19 |
* |
| 20 |
* Field layout of a document (fixed — the schema is created by this class): |
| 21 |
* _id same ids as the classic index (md5(source_url), <md5>_chunk_N, manual_*) |
| 22 |
* text the chunk text, full-text indexed (string field, language from settings) |
| 23 |
* embedding the dense vector, dimension = the active embedding model's (client-supplied) |
| 24 |
* everything else (source_url, type, bot_id, chunk_index, total_chunks, is_chunked, |
| 25 |
* parent_url_hash, role_restriction, created_at, last_updated) = auto-indexed metadata. |
| 26 |
* |
| 27 |
* Response shapes measured 2026-09-19 against a live document index: |
| 28 |
* search → {matches:[{_id,_score,<fields…>}], namespace, usage} (fields are FLAT on the hit) |
| 29 |
* fetch → {documents:{<id>:{_id,<fields…>}}} (embedding included unless include_fields) |
| 30 |
* list → POST body {prefix,limit,pagination_token} → {documents:[{_id}], pagination:{next}} |
| 31 |
* upsert → 202 {upserted_count}; delete → 202 {}; a classic /query on a document index → 400. |
| 32 |
* Numeric fields come back as floats (chunk_index 0.0) — normalize_metadata() casts them. |
| 33 |
* A dense score_by cannot be combined with a text score_by in one search; hybrid is |
| 34 |
* a dense search plus a text-match FILTER, or two searches fused client-side. |
