How can I get search results from multi-line columns in a list (in the sharepoint online site)?

Question

I've created a list which contain some multi-line columns. A key word is list on the multi-line column. Yet when I type in the key word in the search box. The search result is blank.

Answer 1

I have tested and confirmed that keywords in multi-line columns will be returned in search results in SharePoint Online.

However, quoting the official document Manage the search schema in SharePoint - Crawling and re-indexing:

In SharePoint in Microsoft 365, crawling happens automatically based on the defined crawl schedule.

This is managed by Microsoft directly and cannot be monitored or modified from our end.
You will have to wait until the column values are crawled so that they get returned in search results.
