WP_Query with OR conditions

Here is an issue, I have a site that has sort of complex search. I have set several arguments: s, meta_query, tax_query and post_type

Obviously these are all linked with AND relationships (except meta_query and tax_query that can be set with OR relationship, but I need to get posts that have entered phrase at either title or content or some of meta values, or some of taxonomies.

Any way of doing so?
