Jekyll Algolia Plugin - nodes_to_index

I’m facing an issue with indexing my Jekyll-based static site (a blog) properly with jekyll-algolia plugin.

On my site, every blog article content is wrapped in <section class='page__content'> ... </section>. I have a post which contains a bunch of links and has the following structure:

<section class="page__content">

    <h2>Header 1</h2>
            <li><a href=''>Link 1</a></li>
            <li><a href=''>Link 2</a></li>

    <h2>Header 2</h2>
            <li><a href=''>Link 3</a></li>
            <li><a href=''>Link 4</a></li>


But it doesn’t index any content from inside the section of that post.

I added nodes_to_index: 'p,section.page__content' in my configuration, but it didn’t make any difference from the default <p>.

Further, I changed the configuration to nodes_to_index: 'p,h2,section.page__content'. With this, it indexed just the text of “Header 1”, but “Header 2” was not indexed, and neither were the links (1 to 4).

If I want to index all the content inside the section, what do I need to do?
