What?

go-queryparser parses a common "q" http GET variable to strip out filters, which can be used for advanced searching, like:

Hello World tags:example,world foo:"something quoted" author:lrstanley

Use:

go get -u github.com/lrstanley/go-queryparser/v3@latest

Example:

package main

import (
	"fmt"
	"net/http"

	"github.com/lrstanley/go-queryparser/v3"
)

func main() {
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		q := queryparser.Parse(r.FormValue("q"))
		if q.Has("author") {
			fmt.Fprintf(w, "filtering by author %q!", q.GetOne("author"))
			return
		}

		fmt.Fprint(w, "no filtering requested!")
	})

	http.ListenAndServe(":8080", nil)
}
$ curl -s localhost:8080
no filtering requested!
$ curl -s 'localhost:8080?q=author:"liam"'
filtering by author "liam"!

The main benefit is for user input boxes where you want additional filtering, like the Github issues search box, or similar.
