Configures and debugs Apache Solr search for TYPO3, including EXT:solr, configsets, indexing queues, Tika/file indexing, facets, suggest, routing, PSR-14 events, custom indexers, vector search, and frontend search UI. Use when the user mentions Solr, EXT:solr, indexing, facets, autocomplete, suggest, Tika, solrfal, search debugging, or vector search in TYPO3.

Compatibility: This skill targets TYPO3 v14.x. Match EXT:solr (and Solr server version) using the official Version Matrix and Packagist — 14.0.x availability may lag docs; use the branch/matrix the project documents until a stable tag ships.
All custom PHP examples use TYPO3 v14 conventions (PHP 8.2+, constructor promotion, where shown).
#[AsEventListener]
TYPO3 API First: Always use TYPO3's built-in APIs and EXT:solr's TypoScript/PSR-14 events before creating custom implementations. Do not reinvent what EXT:solr already provides.
Sources
This skill is based on the following authoritative sources:
EXT:solr connects TYPO3 CMS to an Apache Solr search server, providing full-text search, faceted navigation, autocomplete, and (on supported Solr 9.x builds) dense-vector / semantic features where enabled.

While 14.0.x has no stable tag on Packagist (betas are published), follow the TYPO3 v14 Readiness subsection below (^14.0@beta / docs workflow) until a stable tag ships.
TYPO3 v14 Readiness
The Version Matrix targets TYPO3 14.3 + EXT:solr 14.0 + Apache Solr 10.0.0 + ext_solr_14_0_0 (Solr 9.10.1 belongs to EXT:solr 13.1/12.1). Upstream development is on main:
main requires typo3/cms-core: ^v14.3.0 (see composer.json on main)
branch alias dev-main -> 14.0.x-dev
Composer reality check:14.0.0-beta1–beta3 are published on Packagist; no stable 14.0 tag exists yet, so install via the @beta stability flag (or fall back to dev-main for the bleeding edge).
Warning: Re-check Packagist/GitHub when you upgrade — switch from ^14.0@beta to a plain ^14.0 constraint as soon as stable releases exist.
CVE-2025-24814 Migration
Apache Solr 9.8.0+ disables loading jar files via lib directive in configsets. CVE-2025-24814 is a remote-code-execution class issue: if an attacker can replace or supply a configset file that Solr treats as trusted, Solr may load attacker-controlled JARs from that configset (including via the lib directive), which can lead to arbitrary code execution. The stricter default blocks that classpath loading from configsets. The solr-typo3-plugin must be moved from /configsets/ext_solr_*/typo3lib/ to /typo3lib/ at the Solr server root. Docker users: use the EXT:solr container image 13.0.1+ (image tag, not TYPO3 Core) so this migration runs automatically.
3. Installation & Setup
Composer
composer require apache-solr-for-typo3/solr
DDEV Setup
The recommended local development setup uses the ddev-typo3-solr addon:
ddev add-on get ddev/ddev-typo3-solr
ddev restart
Solr image version: the DDEV Solr add-on defaults SOLR_BASE_IMAGE to solr:9.10, and the generated compose file is .ddev/docker-compose.typo3-solr.yaml. For explicit control, override via .ddev/.env.typo3-solr (for example: ddev dotenv set .ddev/.env.typo3-solr --solr-base-image="solr:9.10.1") and rebuild the Solr service.
Auto-initialize cores on boot in .ddev/config.yaml:
hooks:post-start:-exec-host:ddevsolrctlapply
Useful DDEV commands:
Command
Description
ddev solrctl apply
Create cores from config
ddev solrctl wipe
Delete all cores
ddev exec -s typo3-solr solr --version
Check Solr version inside the Solr service
ddev launch :8984
Open Solr Admin UI
ddev logs -s typo3-solr
View Solr logs
Docker (Production)
services:solr:# Note: as of March 2026, no stable 14.0 tag exists on Docker Hub.# Use 14.0.x-dev for testing, or 13.1 for production until 14.0 ships.image:typo3solr/ext-solr:14.0.x-devports:-"8983:8983"volumes:-solr-data:/var/solrrestart:unless-stoppedvolumes:solr-data:driver:local
The image ships default cores for all languages. Persistent data is stored at /var/solr (owned by UID 8983).
Standalone Solr
Deploy the configset from EXT:solr into your Solr installation:
Create cores via core.properties files, solrctl, or the Solr Admin API. Payload shape differs by Solr major (v8 vs v9 “v2” APIs) — treat any one-liner curl as illustrative and follow the Solr version you run.
# Illustrative only — confirm against your Solr admin API docs / use bin/solr or ddev solrctl for local setups
curl -sS -X POST "http://localhost:8983/solr/admin/cores?action=CREATE&name=core_en&configSet=ext_solr_14_0_0"
Managed Hosting: Mittwald
Mittwald provides a managed Solr service via their container platform. Use the Terraform module:
Access Solr at http://typo3-solr:8983 inside the container. For local debugging:
mw container port-forward --port 8983
Managed Hosting: hosted-solr.com
hosted-solr.com by dkd provides pre-configured Solr cores optimized for EXT:solr. As of the live pricing page, the Small plan is 10,00 EUR/month (2 Solr indexes, 4.000 documents; VAT note on site). After creating a core, configure it in your TYPO3 site config using the provided host, port, and path.
In config/system/additional.php, override site config values programmatically or use a post-processing approach. For simple setups, keep .env values and reference them in deployment scripts that generate site config YAML per environment.
4. EXT:tika -- When You Need It (and When Not)
EXT:tika integrates Apache Tika for metadata extraction, language detection, and text extraction from over 1,000 file formats.

Yes
Standalone Docker container, newest Tika version
Solr Cell
Acceptable

Tika App
Deprecated

When you NEED EXT:tika:
File indexing via EXT:solrfal (search inside PDFs, Word documents, etc.)
Only indexing pages and structured records (news, events, products) via Index Queue
EXT:solr handles page content and record fields natively without Tika
Version: EXT:tika 13.1 (the current v13 release) requires Apache Tika Server/App 3.2.3+. A v14-compatible EXT:tika release is not yet available on the official Version Matrix — track Packagist and GitHub for updates. For Apache Tika and Solr security advisories, verify on Apache Solr security / vendor advisories.
