Not able to get my custom search result using meta_query and tax_query together?

Looks like a common problem: meta_query & tax_query combined = fail. Look, i’ve the same problem and i mentioned two links (possible solutions for you) in my question (Combine tax_query and meta_query in WP_Query). Can you use/handle something of this? If yes, maybe it’s your solution.
