Searching by language
Stay organized with collections
Save and categorize content based on your preferences.
To restrict your search results to a specific language, use the
language or lang filter. For example, the following
search restricts the search results to the Java language:
helloworld language:java
You can also use the file filter, as shown in the following example:
file:\.java
Remember that searches use regular expressions by default. As a result, the
following search doesn't work:
*.java
Instead, try the following searches:
\.java
lang:java
