When you search an error message on google, wrap it in quotes. This tells google to search for an exact match. Otherwise it'll just look for synonyms and related terms.
If you want google to show results from a specific site use: site:YourSiteHere followed by the search term
e.g. site:stackoverflow.com yourSearchTermHere
You can exclude stuff from the results by using the minus sign:
e.g. Don't return results using jquery: how to grab an element from the dom -jquery
To ensure you don't get information from obsolete sources, use the "after" keyword: 'tableViews after:2020'
This is handy when maintaining a legacy project: 'yourSearchTermHere before:2020'
Simply use two dots:
2015..2020$10..$20#..#
e.g.
angular 2 announement 2013..2015
Use the pipe operator "|"
(A|B)
You can even add a third thing like so:
(A|B)C
You also have the wildcard option (an asterisk) which stands for "ALL".
e.g.
How to build * with css
In the example below you can find all the subdomains of a website:
site:*fireship.io -www
You may also want a specific filetype:
filetype:pdf
Find competitor websites to the one you are looking at:
related:url
related:angular.io
cache:url
cache:yourWebsiteHere.com`(you will see your website the way google sees it)
