Summarize shortcode filters

I’ve been able to created a shortcode for a specific search field, such as:
Itineraries (for the post type) and Nepal (for the category term). Here’s the code so far:

[summarize_posts post_type=”itineraries” taxonomy=”category” taxonomy_term=”nepal” order=”ASC” orderby=”post_title” ]

However, I need the search to go beyond just Nepal, but Tours of Nepal. How would I go about that?

Thanks in advance for your help.
