Search not searching certain words - how to fix?
Try to specify the fields you need to search.
{% set queryParams = {
        search: {
            query: 'title:*' ~ name ~ '* OR description:*' ~ name ~ '* OR previewText:*' ~ name ~ '* OR tag:*' ~ name ~ '*'
        }
    } %}

{% set entries = craft.entries(queryParams).section('entries').all() %}
