Enclosing a word or phrase between double quotes tells Google to search for the exact term / phrase and make it "mandatory". In the early days of Google to indicate that a term must be included, the
+(plus) symbol was used, but this symbol is no longer used as a search operator.
If you're looking for pages having multiple words, type them one after the other; there is no need to add a symbol or operator.
- Whenever it be convenient, type a well-constructed sentence or question.
- If you will write a keyword-style query, add the most important keywords (terms) first.
Below each result, it might show a line telling you if the result doesn't contain all the terms. If a term is missing, it will tell which term is missing and will show a link after the label "Show results with" with the missing term's text.
Click on it to refine the search to include the missed term.
Google's mindset is that presenting the page "About 0 results" means bad business for them, as there are no ads / paid content to show, and it might be disappointing for most users.
In old versions of the Google Search help articles, the symbol
* as a wildcard and
AROUND(value) were mentioned but are no longer mentioned. The documentation only uses the Advanced Search.
The field terms appearing:, has as default option anywhere on the page. Try in the text of the page. This will add the operator allintext: at the beginning of the query.
