Welcome to the first issue of the Software Mastery newsletter.

In this issue, I want to share two tips about how to search effectively on Google.

Googling is a fundamental skill for software engineers, so much so that it’s a meme:

Engineers use Google for various reasons:

1. They forgot how to do something in a particular programming language.

2. They want to understand an error they’re seeing.

3. They need to learn about some engineering concepts.

Googling is a way to find resources, but ultimately, whether we’re able to find what we’re looking for depends on our search query.

Sometimes, the resource we’re looking for is out there, but Google isn’t ranking it highly enough in the search results for us to see it.

To refine a search query, here are two tips to get started:

Use the site: operator to restrict results to a particular site.

Use the after: operator to filter outdated results.

The site: Operator

For certain search queries, we’re only interested in results from specific websites. To force Google to only show us results from a particular website, we can add site: to a search query, followed by the website.

If you, for example, are particularly interested in what the people of Hacker News have to say about working at Google, you could write a search query like:

working at Google site:news.ycombinator.com

Here’s a more practical example. Suppose you’re developing on an EC2 instance and just ran docker build -t my-project . to create a Docker image for your application. After a few minutes, the command fails with the following error message:

> docker build -t my-project .
Unable to find image 'python:latest' locally

 1): write /usr/share/doc/libfreetype6/reference/ft2-type1_tables.html: no space left on device.

To filter Google’s search results for Stack Overflow posts, you could write the following search query:

docker no space left on device site:stackoverflow.com

This type of query can be useful sometimes if websites other than Stack Overflow are ranking highly for this particular search query but do not contain what you’re looking for.

The after: Operator

Software engineering moves fast. As new versions of programming languages, frameworks, and libraries get released, tutorials and other resources get outdated quickly.

To retain search results after a certain year, we can add the after: operator to a search query, followed by a year, year-month, or year-month-day.

For example, if you’d only like to see Spring Boot tutorials written in 2024, you can write a search query like:

spring boot tutorial after:2023

Here’s another example that combines the after: operator with the site: operator.

Suppose I’m interested in what OpenAI has been up to in the past month, and I’m particularly interested in discussions about OpenAI on Reddit. I can find recent OpenAI-related Reddit posts with:

openai after:2024-07 site:reddit.com

Your Turn!

I hope this week’s issue gave you some ideas on how you can use Google’s search operators to find what you need on the Internet.
