Sd Navigate Pages

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:

() => {
  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:

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.
