+Package dorkgen is a Go package to generate dork requests for popular search engines such as Google, DuckDuckGo and Bing.
+It allows you to define requests programmatically and convert them into string.
+You can use it as following:
+
+package main
+
+import "github.com/sundowndev/dorkgen"
+
+func main() {
+	dork := &dorkgen.GoogleSearch{}
+	// dork := &dorkgen.DuckDuckGo{}
+	// dork := &dorkgen.Bing{}
+
+	dork.Site("example.com").Intext("text").ToString()
+	// returns: site:example.com "text"
+}
