# 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.

Example request shape:
|
|
|
|
```http
|
|
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.
