How to Crawl the metadata for pages

Question

I need to crawl the data of fileRef. How to handle to proceed with that? This information is contained inside the pages. Can anyone assist with this?

{
    "odata.type": "SP.Data.PagesItem",
    "odata.id": "Web/Lists(guid'e742e0aa-ff77-42b2-9660-6aaa975e03ab')/Items(6)",
    "odata.etag": "\"35\"",
    "odata.editLink": "Web/Lists(guid'e742e0aa-ff77-42b2-9660-6aaa975e03ab')/Items(6)",
    "Id": 6,
    "Title": null,
    "ID": 6,
    "FileRef": "/sites/pnp/Pages/atozindex.aspx"
}

Answer 1

If the content is be regarded as the content in the page, then it will be crawled in the page.

If the content is in one web part in the page, then the content will not be crawled.

And in SharePoint online environment, the crawl will run automatically.
