Add an example of paginated searches

[ilyazub]

There is no documentation for paginated searches. For example, the Python wrapper has such documentation.

Pagination can be done like this:

// Try it online: https://replit.com/@serpapi/scrape-google-organic-results-urls-nodejs-serpapi

const SerpApi = require("google-search-results-nodejs");
const search = new SerpApi.GoogleSearch(process.env["API_KEY"]);

const params = {
  q: "watch movies online free",
  location: "Austin, TX",
};

function paginationCallback(result) {
  console.log(`\nCurrent page: ${result.serpapi_pagination.current}\n`);

  for (organicResult of result.organic_results) {
    console.log(organicResult.link);
  }

  const num = params.num || 10;

  search.json(
    {
      ...params,
      start: result.serpapi_pagination.current * num,
    },
    paginationCallback
  );
}

search.json(params, paginationCallback);

Sample output

Also some search.pagination() wrapper can be added like for Python: serpapi/google-search-results-python#19.
