# ScienceDirect Pagination & Sorting

Navigate between result pages, change sorting, or adjust results per page.

## How pagination works

ScienceDirect uses URL parameters for pagination:
- `offset` — starting result index (0-based). Default is 0 (page 1).
- `show` — results per page. Options: `25`, `50`, `100`.
- `sortBy` — sort order. `date` for newest first; omit for relevance.

Page calculation: `page N` → `offset = (N - 1) * show`

## Steps

### Step 1: Determine current state

Use `evaluate_script` to read the current URL and pagination info:

```javascript
() => {
  const url = new URL(window.location.href);
  const params = Object.fromEntries(url.searchParams);
  const pageInfo = document.querySelector('.Pagination li:first-child')?.textContent?.trim() || '';
  const totalText = document.querySelector('.search-body-results-text')?.textContent?.trim() || '';
  return { params, pageInfo, totalText, currentUrl: window.location.href };
}
```

### Step 2: Build target URL

Based on `$ARGUMENTS`, modify the URL parameters:

| User intent | Action |
|-------------|--------|
| "next" / "下一页" | `offset += show` |
| "prev" / "上一页" | `offset -= show` (min 0) |
| "page 3" / "第3页" | `offset = (3-1) * show` |
| "sort by date" / "按日期排序" | add `sortBy=date` |
| "sort by relevance" / "按相关性排序" | remove `sortBy` |
| "show 100" / "每页100条" | set `show=100`, reset `offset=0` |

### Step 3: Navigate and extract

Use `navigate_page` to the new URL. **Always include `initScript`** to prevent bot detection:
```
initScript: "Object.defineProperty(navigator, 'webdriver', {get: () => undefined})"
```

Then extract results using `evaluate_script` with built-in waiting (same as `sd-search`). Do NOT use `wait_for` — it returns oversized snapshots.

## Notes

- Always preserve existing query parameters (`qs`, `tak`, `authors`, etc.) when modifying pagination/sort.
- When changing `show`, reset `offset` to 0 to avoid out-of-range pages.
- Maximum 2-3 tool calls per operation.
