Help implementing search function

I'm using Grav for a website that it works very well. Except I have not been successful in using the search function at all. Oddly, I'm using Grav to access data stored in a yaml file in the data folder. So ALL my pages look like this:

{% for item in page.header.imports %}
  {% if item.Chapter == 5 %}
  Heb {{ item.Chapter }}:{{ item.Verse }}  {{ item.Context }}</br>
  {% endif %}
 {% endfor %}

After it pulls the data from the yaml file, it is actually an entire chapter from the Bible. This makes it very fast to roll out the site, but the bad side affect is NO SEARCH capabilities. If you know how to make search, or even caching work after the page is rendered, that would be wonderful. I would appreciate any pointers.
