Die Hauptmodelle von Claude und Codex werden dabei nicht ersetzt. + +## Installation + +Voraussetzungen: macOS oder Linux (ARM64/x86_64), Git, Python **3.10+** mit venv. +Windows: innerhalb von WSL installieren. Kein sudo, kein pip und keine +Python-Paketdownloads erforderlich.

Für **ask** muss +[Ollama](https://ollama.com/download) separat installiert und gestartet sein: + +~~~sh +ollama serve +~~~ + +Bei laufender Ollama-App ist kein zweiter Server nötig. In einem weiteren Terminal: + +~~~sh +ollama list +# Nur falls das Modell fehlt: mehrere GB Download +ollama pull srchmnmichael/qwen3.5-9B-uncensored:latest +local-search doctor +~~~ + +Dieses Modell ist die Voreinstellung. Ein anderes installiertes Modell wählen: + +~~~sh +local-search model qwen3.5:latest +~~~ + +Modell und Loopback-URL stehen in ~/.config/local-search/config.json. +Vor jeder Modellanfrage werden die Ollama-Metadaten geprüft: Cloud-Modelle, +Remote-Aliasse und Modelle ohne erkennbare lokale Gewichte werden abgewiesen. +Der Installer lädt weder Ollama noch Modellgewichte ungefragt herunter. +Modellgewichte sind nicht Teil dieses MIT-Projekts; ihre eigenen Lizenzbedingungen +gelten.

Normale Ignore-Regeln gelten auch außerhalb +eines Git-Repositories. Symlinks werden nicht verfolgt. + +Versteckte Nachkommen werden nicht indexiert: tgrep 1.0.5 unterstützt +serve --hidden nicht.

Standardmäßig höchstens 40 Treffer. --limit 100 erhöht das Limit. +Zeilentexte sind auf 2.000 Zeichen begrenzt; ask erhält höchstens rund 12.000 +JSON-Zeichen Quellenkontext und führt maximal drei Suchbegriffe pro Wurzel aus. + +Ein laufender Index ist **eventuell konsistent**. Während Aufbau oder erkennbar +gestörter Aktualisierung wird frisch mit ripgrep gesucht. --fresh erzwingt das +auch für wichtige Negativbefunde. Ein gleichzeitig verändertes Dateisystem ist +kein atomarer Snapshot. ripgrep und tgrep können bei Randfällen ihrer +Ignore-/Binärbehandlung abweichen. + +Exitcodes: **0** Erfolg/Treffer, **1** keine Treffer, **2** Fehler, +**130** abgebrochen. Ollama-Ausfall ist ein Fehler bei ask; search bleibt nutzbar. + +In Claude Code: /local-search. In Codex: $local-search. +Bei expliziten Vorgaben „immer zuerst rg“ muss die übergeordnete Regel eine +Ausnahme erlauben; der Skill überschreibt sie nicht. + +**Datengrenze:** tgrep und Qwen arbeiten lokal. Ausgaben, die ein Claude-/Codex-Agent +liest, gelangen dennoch in dessen Kontext. --paths-only unterdrückt Ausschnitte +und generierte Antworten, nicht Dateinamen. Bei ask --paths-only wird nur die +Frage zur lokalen Suchplanung an Ollama geschickt. + +## Wartung + +~~~sh +local-search stop home +local-search index home # vollständiger Neuaufbau mit anschließendem Start +local-search remove backend # Registrierung entfernen, Index behalten +~~~ + +Konfiguration: ~/.config/local-search/config.json. +Indizes/Status/Serverlogs: ~/.local/share/local-search/indexes/. +XDG_CONFIG_HOME und XDG_DATA_HOME werden unterstützt. +Eine geänderte Wurzelkonfiguration bekommt einen neuen Indexpfad.
