# case.dev Search

Unified search across web, legal databases, case law, patents, vault contents, and the case.dev skills knowledge base.

Requires the `casedev` CLI. See `setup` skill for installation and auth.

## Web Search

```bash
casedev search web "employment discrimination California" --json
casedev search web "SEC enforcement actions 2024" --limit 20 --json
```

Flags: `--limit` (default: 10), `--news`, `--type` (search|news), `--include-domain`, `--exclude-domain`.

## Web Fetch

```bash
casedev search webfetch "https://example.com/ruling.html" --json
```

Flags: `--livecrawl`, `--subpages`, `--subpage-target N`, `--max-chars N`, `--timeout N`, `--context`, `--no-summary`, `--fallback`.

Multiple URLs: `casedev search webfetch URL1 URL2 --json`

## Legal Search

```bash
casedev search legal "breach of fiduciary duty" --json
casedev search legal "ERISA preemption" --jurisdiction "federal" --json
```

Flags: `--jurisdiction`, `--limit` (default: 10), `--deep`, `--alt-query` (repeatable, for deep mode).

Deep mode example:
```bash
casedev search legal "force majeure pandemic" --deep \
  --alt-query "impossibility of performance COVID" \
  --alt-query "frustration of purpose" --json
```

## Case Search

### By query
```bash
casedev search cases "wrongful termination retaliation" --json
```

### By similarity
```bash
casedev search cases --url "https://casetext.com/case/example-v-example" --json
casedev search cases --url "https://example.com/case" --after "2020-01-01" --json
```

Flags: `--jurisdiction`, `--limit` (default: 10), `--url` (similarity mode), `--after` (date filter).

## Patent Search

```bash
casedev search patent "machine learning NLP" --json
```

Flags: `--assignee`, `--inventor`, `--status`, `--type`, `--filing-from`, `--filing-to`, `--offset`, `--limit` (default: 25).

## Vault Semantic Search

```bash
casedev search vault "indemnification clause" --vault VAULT_ID --json
```

See `vaults` skill for full vault search documentation.

## Skills Knowledge Base

```bash
casedev skills search "contract review" --json
casedev skills read SKILL_SLUG --json
casedev skills read SKILL_SLUG --content-only
```

## Troubleshooting

**No legal results**: Try broader terms, remove jurisdiction filter, or use `--deep` mode with `--alt-query` variations.

**Web fetch unavailable**: Use `--fallback` to fall back to web search.
