Alias as first term of hierarchy in search

I take my class notes on logseq and it has been great, and using hierarchical tagging has been a huge boost in future referencibility. Though not necessary I was wondering a parent page’s alias is set to be included in key word searches:

alias:: stomach

future me wants to look for: contents of “gastric/acid” using the search tool. Is there an implementation that would pull up this page if I were to search “stomach/acid”
