**Pre-indexed sites useful for research:**

| Site | area_id | Key Selectors |
|------|---------|---------------|
| arXiv Advanced Search | `arxiv.org:/search/advanced:default` | **40+ selectors**: field select, term input, category checkboxes (CS/Physics/Math/...), date range filters, cross-list control — used in Step 3 |
| ar5iv paper | `ar5iv.labs.arxiv.org:/html/{paper_id}:default` | `h1.ltx_title_document` (title), `div.ltx_authors` (authors), `div.ltx_abstract` (abstract), `section.ltx_section` (sections) |
| Google Scholar | `scholar.google.com:/:default` | `#gs_hdr_tsi` (search input), `#gs_hdr_tsb` (search button) |
| arXiv homepage | `arxiv.org:/:default` | Global search across 2.4M+ articles |

**For any URL you plan to visit**, run `actionbook search "<keywords>" -d "<domain>"` to check if it's indexed. Use indexed selectors when available; fall back to `actionbook browser snapshot` for unindexed sites.

**Example: Get arXiv Advanced Search selectors before searching:**

```bash

undefined

undefined

**Example: Search by title keywords in a date range:**

```bash
actionbook browser open "https://arxiv.org/search/advanced"

undefined

undefined

Parse the search results to extract URLs and snippets. Collect the top 5-10 most relevant URLs. For each discovered URL, query Actionbook API (Step 2 pattern) to check if the site is indexed before visiting.

actionbook browser open "<url>"
actionbook browser text                # Full page text (fallback)
actionbook browser text "<selector>"   # Use Actionbook selector if indexed

undefined

**Key lesson:** Don't rely solely on ar5iv. Always cross-reference 3-4 sources for completeness.

**For Google Scholar** (indexed by Actionbook):

```bash
actionbook browser open "https://scholar.google.com"

**For unindexed sites**, use snapshot to discover page structure:

```bash
actionbook browser open "<url>"
actionbook browser snapshot            # Get accessibility tree to find selectors
actionbook browser text "<discovered_selector>"

If all fail, save the JSON file and inform the user of its path.
