Algolia helper searcher method Filter doesn't filter strings but filters numericals only
<p>I'm using Algolia-helper-swift [0.1] with Algolia-client-swift [3.7] since im using xcode 7.3.1 and swift 2.0+ and my json structure snippet is as follows</p>

<pre><code> "-KTKNoEhrdaBShtXJGM8" : {
"Book_name" : "Hello World",
"Book_price" : 7273,
"uploaded_by" : "John" }
</code></pre>

<p>Trial 1</p>

<pre><code>{
  "params": "facetFilters=[]&amp;filters=Book_price%3E0%20AND%20uploaded_by:John&amp;hitsPerPage=8&amp;page=0&amp;query=&amp;restrictSearchableAttributes=[%22Book_name%22]"
}
</code></pre>

<p>Trial 2</p>

<pre><code>{
  "params": "facetFilters=[]&amp;filters=Book_price%3E0%20AND%20uploaded_by:%22John%22&amp;hitsPerPage=8&amp;page=0&amp;query=&amp;restrictSearchableAttributes=[%22Book_name%22]"
}
</code></pre>

<p>Trial 3</p>

<pre><code>{
  "params": "facetFilters=[]&amp;filters=Book_price%3E0&amp;hitsPerPage=8&amp;page=1&amp;query=&amp;restrictSearchableAttributes=[%22Book_name%22]"
}
</code></pre>

<p>Trial 4</p>

<pre><code>{
      "params": "facetFilters=[]&amp;filters=uploaded_by:%22John%22&amp;hitsPerPage=8&amp;page=0&amp;query=&amp;restrictSearchableAttributes=[%22Book_name%22]"
    }
</code></pre>

<p>The Trial 1,2 &amp; 4 don't work returns me 0 results/hits
the third however works but its a numerical logic.
Please if someone could help me with this it would be great.</p>
