Function vanilla_frontend_search_where_replace_placeholder
Extends the original database search SQL query in order to take into account extended data associated with each post. The extended data can be post meta values and/or term names of taxonomies associated with each post. Meant to be used as a filter callback in order to extend the original database seach SQL query.
A placeholder has earlier on in the code been injected by the function
vanilla_frontend_search_where_inject_placeholder(). This function is
supposed to run at a reasonably high priority (late), so that the
conditions that it injects are not likely to be matched by regexp lookups
of third party code, as a false-positive.
