Search in the specific file types - kiril-dragomirov/PHPStorm GitHub Wiki

Use the File Mask option to narrow your search to a specific file type. You can select the existing file type from the list, add a new file type, or add an additional file mask syntax to search for file types with certain patterns.

To Invoke search engine double press SHIFT.

1. In the Find in Path dialog, select the File Mask checkbox and from the list of file types, select the one you need.

2. If you don't find the file type you need in the list, enter your file type in the File Mask field.

For example, use the following syntax to search only in markdown files: *.md.
