title: Angular 8 Multi phrase search using ng2-pdf-viewer
body: <p>I'm working on an angular8 application and displaying a PDF using ng2-pdf-viewer library. Currently, I'm able to search the PDF for a single phrase using the code below.</p>
  
  <pre><code>searchQueryChanged(searchStr: string) {
      if(searchStr != null &amp;&amp; searchStr.length &gt; 0) {
        console.log("searchStr1 ::: ", searchStr);
        this.pdfComponent.pdfFindController.executeCommand('find', {
          highlightAll: true,
          caseSensitive: true,
          findPrevious: false,
          phraseSearch: true,
          query: searchStr
        });
      }
    }
  </code></pre>
  
  <p>I'd like to know if it is possible to <strong>search for an array of strings/phrases and highlight them all at the same time using ng2-pdf-viewer library</strong> or is there a much better way to highlight multiple strings in a given PDF.</p>
  
  <p>Thanks,
