title: how to set multiple values for query params in vue-router's router-link
body: <p>Using <code>vue-router</code>'s <code>&lt;router-link&gt;</code>, I want to redirect a user to a path like so <code>/projects/7363994/posts?t=apples+oranges&amp;s=all</code>.</p>
  
  <p>Where <code>t</code> means topics, and <code>s</code> means sources (facebook, twitter, forums etc).</p>
  
  <p>ie for project 7363994, look for posts whose topics includes <code>apples</code> and <code>oranges</code> and from <code>all</code> sources.</p>
  
  <p>such that, on page load for <code>/projects/:id/posts</code> endpoint, the component will first check for those params and make queries to an API for data according to those param values.</p>
  
  <p>this is what I have tried:</p>
  
  <pre><code>&lt;router-link 
      :to='{
          path: `posts`, 
          query: { 
              t: "apple+orange",
              s: `all`
          }
      }'
      append
  &gt;
  &lt;/router-link&gt;
  </code></pre>
  
  <p>which gives me <code>/projects/7363994/posts?t=apples%2Boranges&amp;s=all</code>.</p>
  
  <p>i was expecting the link to show up as:
  <code>/projects/7363994/posts?t=apples+oranges&amp;s=all</code></p>
  
  <p>but instead, it is showing:
  <code>/projects/7363994/posts?t=apples%2Boranges&amp;s=all</code></p>
  
  <p>notice that the <code>+</code> symbol has been replaced with <code>%2B</code></p>
  
  <p>why is that so? am I supposed to do some escaping?</p>
  
  <hr>
  
  <p>also tried this:</p>
  
  <pre><code>&lt;router-link 
      :to='{
          path: `posts`, 
          query: { 
              t: ["apple", "orange"],
              s: `all`
          }
      }'
      append
  &gt;
  &lt;/router-link&gt;
  </code></pre>
  
  <p>gives me <code>/projects/7363994/posts?t=apples&amp;t=oranges&amp;s=all</code></p>
  
  <hr>
  
  <p>I tried escaping the <code>+</code> symbol, but that doesn't seem to work as well.</p>
  
  <p>anyone knows how this works? does <code>vue-router</code> even allow this to begin with?</p>
  
  <p>thanks!</p>
