A short snippet providing two functions to process a Google search query from the console while on www.google.* website.

google-search-script.js

function searchGoogleForString(searchStr) {
    var baseLink = "https://" + window.location.hostname + "/search?q=" + searchStr;

    var xhr = new XMLHttpRequest();
    xhr.open("GET", baseLink, true);

    xhr.onload = function () {
        if (xhr.readyState === 4 && xhr.status === 200) {
            var d = document.createElement("div");
            d.innerHTML = xhr.response;
            var resNodes = d.querySelectorAll("div#resultStats");

            if (!resNodes || resNodes.length !== 1) {
                throw "resNodes is invalid, perhaps Google changed their HTML...";
            }

            var resultStats = resNodes[0];
            var text = resultStats.childNodes[0].wholeText;
            var searchCount = Number(text.split(" ")[1].replace(/\./g, ""));

            console.log("Count for '" + searchStr + "': " + searchCount);
        } else {
            throw "Web request to Google failed...";
        }
    };

    xhr.send(null);
}

function searchGoogleForStrings() {
    if (arguments.length < 1) {
        throw "Could not search as no words were provided. Enter comma delimited strings to search Google.";
    }
    console.log("Querying...");
    var searchWords = arguments;

    for (var i = 1; i <= searchWords.length; i++) {
        // capture variable i to local scope...
        var sec = i;
        var sw = searchWords[sec-1];

        if (typeof sw !== "string"){
            console.warn("Skipping parameter #" + sec + " as it is not type of string.");
            continue;
        }

        // min delay of 500ms
        var timeout = Math.round(((Math.random() * 2000 * sec) + (500)));
        setTimeout(searchGoogleFor.bind(this, sw, sec == searchWords.length), timeout);

        if (sec == searchWords.length) {
            setTimeout(function(){ console.log("Processing last query..."); }, timeout + 1);
        }
    }
}
