Complex nested arrays search with boosting - elasticsearch

Question

So I have an elastic index with a few thousand docuemnts each with the following rather complex structure which I need to search as follows:
lets say I have the following search string : "I am single and have a dog", I need to be able to
search all doc.ratedTags.tags.keywords and all doc.describedTagCombos.tags.keywords, but giving a boost to matched doc.ratedTags.tags.keywords where its rating sibling has a higher value
tbh i don't think its even possible
