I figure this sub may be interested in this. I wrote a Node.js script to search ELR for multiple keywords and show the recipes which contained every keyword. To use this you must have Node.js installed.

Instructions

1. Create a directory with the two files below in it.

2. Open a Node.js command shell and change to the directory you created.

3. Run 'npm install'

4. Run 'npm start'

The script will list the recipes which contained all search terms. To modify the search just edit the terms variable on line 6 and run again. It's not pretty but it works.

File #1: package.json

  "name": "eltest",
  "version": "1.0.0",
  "description": "Multi-keyword search for e-liquid-recipes.com",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },

  "dependencies": {
    "async": "^1.5.0",
    "lodash": "^3.0.0",
    "x-ray": "^2.0.2"
  }
}

File #2: app.js

var async = require('async');
var _ = require('lodash');
var Xray = require('x-ray');
var x = Xray();

var terms = ["papaya", "kiwi"];
var recipes = [];

async.each(terms, function (value, callback) {
  x('http://e-liquid-recipes.com/list?q=' + value + '&exclsingle=1&sort=score&direction=desc', 'table.recipelist span.mlink', [{
    'name': 'a',
    'href': 'a@href'
  }])
    .paginate('a[rel="next"]@href')
    .limit(10)
    (function (err, data) {
      if (err) return callback(err);
      try {
        recipes.push(data);
      } catch (e) {
        return callback(e);
      }
      callback();
    })
}, function (err) {
  if (err) console.error(err.message);

  var duplicates = _.filter(_.flatten(recipes), function (value, index, collection) {
    var equal = _.where(collection, { href: value['href'] });
    return equal.length > 1;
  })
  console.log(_.uniq(duplicates, 'href'));
});
