title: Using post instead of get in rest-api to be able to use '+' unescaped in regex
body: <p>In my rest-api, I am using regexes. For querying the server, I normally use GET. However, there is the regex situation. With nearly all characters (even those that normally have to be escaped, like '['), this works just fine when using it in the address line, however, with '+', it doesn't. I am thinking about using a POST request instead so I can just specify the regex the body and don't have to escape anything. However, officially, POST requests are only used when changing something. Would it be bad to use a POST request here? Or is there a better solution?</p>
