This also occurs in other ways across Google Search. For example, if someone misspells a word, Google has systems in place that provide the proper spelling to find the web pages and content that match the query. It also occurs when someone doesn't phrase something correctly. The algorithms try to determine the correct word or concept to find a good match.
Google began rolling out the new message this week in the U.S. to let searchers know when Google hasn’t been able to find anything that matches for a specific search. The feature when possible also will provide some alternative searches as well as tips on how you could reformulate your query to better find the information you seek.
Some of those tips include refining web searches with different words or symbols.
Google Search typically ignores punctuation that isn’t part of a search operator. The company also suggests not using
spaces between the symbol or word and search term. For example, a search for
site:nytimes.com will work, but
site: nytimes.com won’t.
