Solr Schema Editor

Purpose

Solr Schema Editor exposes fields used by YaCy's Solr index.

Use it to inspect field availability and advanced schema behavior before changing ranking or import assumptions.

What You Can Do Here

• Solr Schema Editor exposes fields used by YaCy's Solr index.
• Select the narrowest URL, host, field, query, queue, or collection scope.
• Treat deletion, rebuilding, and reloading as maintenance operations with visible search impact.

Page Architecture

Index pages expose stored documents through URL, host, path, Solr field, or queue views. Read-only inspection and destructive maintenance often share the same page, so the target scope matters more than the button label.

Control	Meaning	Values or examples
filter	Filter expression. It decides which records are included, excluded, displayed, exported, or processed on this page.	active, disabled
schema_#[key]#	Choice value. Options: checked.	checked
set	Submits and applies the basic configuration.	Set
reindexSolr	Reindex documents.	reindex Solr

Correct Use

Use inspection before maintenance. First identify the exact URL, host, field, queue, collection, or query scope, then choose the action. Deletion and re-indexing can be expensive or irreversible from the user's point of view, so never broaden the scope just to make a command easier.

Access And Safety

Administrator access is required. YaCy protects _p pages as administration pages.

Protected related endpoint(s): /IndexSchema_p.html, /IndexReIndexMonitor_p.html.

Backend checks: transaction token for protected POST, transaction token issued for forms.

Automation And API

Page backend: source/net/yacy/htroot/IndexSchema_p.java.

Endpoint	Method	Access	Backend
/IndexSchema_p.html	GET	admin	source/net/yacy/htroot/IndexSchema_p.java
/IndexReIndexMonitor_p.html	POST	admin	source/net/yacy/htroot/IndexReIndexMonitor_p.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. Low-level generated parameters are omitted when they are only meaningful inside the rendered YaCy form.

Parameter	Meaning and valid values	Care
filter	Filter text or expression used to narrow the displayed records.	Controls the scope or format of the result. Prefer the narrowest value that answers the request.
schema_#[key]#	Choice value. Options: checked.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
set	Submit action that saves the page settings.	Changes stored data, configuration, or a running job. Use the authenticated action flow where required and verify the result.
reindexSolr	Reindex documents.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.
deleteOnRecrawl	Deletion or termination action. Use only with explicit intent.	Can remove data, stop work, expose access, or make a broad operational change. Use only with explicit confirmation and an exact target.
reindexnow	Reindex documents.	Set only when this option is part of the intended request; otherwise omit it and let YaCy use the page default.

Example request shape:

GET /IndexSchema_p.html?core=...&filter=...&schema_#[key]#=...&schema_solrfieldname_#[key]#=...&set=...

What To Expect

The response should make the selected index scope clearer: records listed, queues changed, errors shown, fields rebuilt, or deletion confirmed. Verify user-visible impact with search after maintenance actions.
