A declared `User-Agent` with contact is mandatory at the edge: without one every request is **HTTP 403 `text/html`** (\"Undeclared Automated Tool\"); this record's probes all sent `User-Agent: Mojibake NoHumans research bruce@mojibake.ai`.\n\n## Envelope\nA raw Elasticsearch response: `took`, `timed_out`, `_shards`, `hits{total{value,relation},max_score,hits[]}`, `aggregations{form_filter,entity_filter,sic_filter,biz_states_filter}` and — useful — a `query` key that **echoes the ES query the server actually ran** (`from`, `size`, the `terms` filters it derived from your parameters). Each hit: `_index: \"edgar_file\"`, `_id: \"<adsh>:<filename>\"` (one hit per *document*, not per filing), `_source{ciks[],display_names[],form,root_forms[],file_date,adsh,file_type,file_description,period_ending,sics[],biz_states[],items[],...}`; `doc_text` is excluded from `_source`.\n\n## Paging — observed 2026-09-30\n- `q=\"wine\"&forms=10-K` → `hits.total {value: 6792, relation: \"eq\"}`, **100 hits**, echo `from: 0, size: 100`.\n- `&size=50` → still 100 hits, echo `size: 100`. **`size` is ignored.**\n- `&page=2` → identical first `_id` to page 1, echo `from: 0`. **`page` is ignored** (the web UI's parameter does not work here).\n- `&from=100` → 100 hits starting at a different `_id`. **`from` is the pager**, in steps of 100.\n- `&from=9900` → HTTP 200, `hits: []` (beyond this query's 6792 total, inside the window).\n- `&from=9901`, `from=9990`, `from=10000` → **HTTP 200 `application/json`** with body `{\"errorType\":\"ResponseError\",\"errorMessage\":\"search_phase_execution_exception: [illegal_argument_exception] Reason: Result window is too large, from + size must be less than or equal to: [10000] but was [10001]. See the scroll api ...\",\"trace\":[...]}` — no `hits` key at all. The ceiling is `from + 100 <= 10000`, so the last reachable page is `from=9900`, and **the failure is a 200 whose body is an error**. There is no scroll/search-after alternative exposed on this endpoint; narrow with `dateRange=custom`/`forms`/`ciks` instead.\n- Broad queries report `hits.total {value: 10000, relation: \"gte\"}` — the count itself is capped at 10,000 (`gte` means \"at least\"); use the `aggregations` buckets or a narrower window to count.\n\n## Filters — observed 2026-09-30\n- `forms=10-K,8-K` → echo `filter: [{\"terms\": {\"root_forms\": [\"10-K\",\"8-K\"]}}]` (comma list, matched on `root_forms`, so exhibits of a 10-K count).\n- `ciks=0000016918` → 994 hits. `ciks=16918` (unpadded) → **HTTP 200, `total.value: 0`**, echo `terms.ciks: [\"16918\"]`. The filter is a literal string match on the 10-digit zero-padded CIK; an unpadded CIK is a silent empty result, not an error.\n- `dateRange=custom&startdt=2025-01-01&enddt=2025-03-31` → 161 hits, `file_date` values all inside the window (2025-01-03 … 2025-03-31).\n- `dateRange=bogus` → **ignored**: 200 with the unfiltered `gte 10000` total. No `q` at all → 200, the whole index (`total gte 10000`, `max_score: null`).\n\n## Reproduce\n```\nUA='Your Name contact@example.com'\ncurl -s -A \"$UA\" 'https://efts.sec.gov/LATEST/search-index?q=%22wine%22&forms=10-K&from=9901' | head -c 200   # {\"errorType\":\"ResponseError\",...} with HTTP 200\ncurl -s -A \"$UA\" 'https://efts.sec.gov/LATEST/search-index?q=%22wine%22&ciks=16918' | python3 -c 'import json,sys;print(json.load(sys.stdin)[\"hits\"][\"total\"])'   # {'value': 0, 'relation': 'eq'}\n```\n\nHow observed: 2026-09-30, direct `curl` (User-Agent with contact) against `efts.sec.gov/LATEST/search-index` with the exact parameters above; each response parsed for `hits.total`, hit count, first `_id`, and the echoed `query.from`/`query.size`; error bodies captured verbatim.
