# Greedy Search > Web/search plus opt-in research via Perplexity, Google AI, ChatGPT, Gemini, Semantic Scholar, and Logically. Grounded all-engine search fetches sources by default; optional configurable synthesis; deep research as separate workflow. Configurable via ~/.pi/greedyconfig. Bing Copilot available for signed-in users. Current docs, recent changes, dependency choices. NOT codebase search. Use when this capability is needed. - Skill: `tomevault-io/greedy-search` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/greedy-search` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/greedy-search/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Research & Search - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/greedy-search --- `greedy_search({ query, engine: "all"|"perplexity"|"google"|"chatgpt"|"gemini"|"semantic-scholar"|"logically"|"bing", synthesize?: bool, synthesizer?: "gemini"|"chatgpt", depth?: "research", breadth: 1-5, iterations: 1-3, maxSources: 3-12, researchOutDir?: string, writeResearchBundle?: bool, visible: bool })` **Modes:** individual engine search · grounded `engine:"all"` search with fetched sources · optional `synthesize:true` using the configured synthesizer over all-engine results · `depth:"research"` for the iterative deep-research workflow. **Config:** `~/.pi/greedyconfig` supports `{ "engines": ["perplexity", "google", "chatgpt", "gemini"], "synthesizer": "gemini" }` by default. `semantic-scholar` and `logically` are opt-in academic/research engines — add them to `engines` only when you want academic paper discovery or research-assistant workflows in the normal all-search fan-out. Without explicit opt-in, `engine:"all"` excludes them because their results are noisy for casual web search; they shine in `depth:"research"` mode. Any configured engine can participate in `engine:"all"`; deep research child searches reuse the same configured `engines` list and stdin-safe query passing. Normal all-search synthesis remains controlled separately by `synthesizer`; research planning/final synthesis uses Gemini. **Compatibility:** legacy `depth:"fast"|"standard"|"deep"` is still accepted. `fast` skips source fetching; `standard`/`deep` alias `synthesize:true`. Prefer `synthesize:true`, optional `synthesizer`, and `depth:"research"` going forward. **Research output:** `depth:"research"` writes a dataroom-style bundle by default under `.pi/greedysearch-research/_/` with `STATUS.md`, `OUTLINE.md`, `reports/SUMMARY.md`, `reports/CLAIMS.md`, `reports/GAPS.md`, `sources/`, and `data/manifest.json`. Pass `researchOutDir` to choose the directory or `writeResearchBundle:false` to disable disk output. **Scale-aware research:** When `breadth` and `iterations` are not explicitly set, the classifier auto-detects query complexity. Simple queries ("what is X") use a fast single-pass path (~70% faster). Moderate queries get tighter breadth/iterations. Complex queries use the full loop. Explicit `breadth`/`iterations` always override the classifier. **Auto-recovery:** Headless default. Bing/Perplexity auto-retry visible on CF block. Manual CAPTCHA → visible stays open; solve then rerun. **CDP safety:** Use `bin/cdp-greedy.mjs` only. Never raw `bin/cdp.mjs`. --- > Source: [apmantza/GreedySearch-pi](https://github.com/apmantza/GreedySearch-pi) — distributed by [TomeVault](https://tomevault.io).
