query
Purpose
query is a peer search/query endpoint.
Use it when another peer or tool submits a search request through YaCy's protocol surface.
What You Can Do Here
- Submit a protocol-level query to a YaCy peer.
- Provide exact query and peer parameters rather than browser-form labels.
- Use the compact response as data for another peer or tool.
Page Architecture
This is a compact endpoint-style page. Its behavior is driven mainly by request parameters and the selected response template, so callers should send only the fields needed for the specific query or peer-service action.
Correct Use
Call the endpoint as a protocol surface. Use exact parameter names and encoded values, authenticate when required, and inspect the response before relying on it. Avoid sending browser-only submit buttons unless the backend explicitly requires the action key.
Access And Safety
This is a peer-service endpoint for YaCy peer communication, not a normal editing page.
Behind a reverse proxy, YaCy accepts X-Real-IP as the effective client and
routing address only when the proxy socket IP matches
server.reverseProxy.trusted and the header contains one valid IPv4 or IPv6
address. Otherwise YaCy uses the socket IP. Authentication and access control
always use the socket IP. The proxy must overwrite, not pass through, any
client-supplied X-Real-IP value.
Automation And API
Page backend: source/net/yacy/htroot/yacy/query.java.
| Endpoint | Method | Access | Backend |
|---|---|---|---|
/yacy/query.html |
GET or POST |
peer-service | source/net/yacy/htroot/yacy/query.java |
Parameter Guide
The table explains values that an agent or script must set deliberately. Parameters not relevant to a task should be omitted or left at the page default.
| Parameter | Meaning and valid values | Care |
|---|
Example request shape:
GET or POST /yacy/query.html?env=...&iam=...&key=...&object=...&youare=...
What To Expect
Expect a compact service response rather than a teaching interface. The response may be XML, RSS, JSON-like text, plain text, or a small HTML template depending on the endpoint.
