Auto-fix wrong search query language/layout

  • Hi. My site is mostly in Russian. Sometimes users search in wrong language, for example they want to type Russian word “привет”, but they type “ghbdtn”.

    When you do this in Google, it say “showing results for привет, search for ghbdtn instead?” Understands wrong layout automatically.

    Same is true if user tried to type in English, but had Russian layout.

    I don’t want Relevanssi to understand what is proper layout for a word. I want it to perform two searches: with query like it is written, and IF no results are found, reverse layout of query (simple 1-to-1 map) and search again. I want it done automatically, server-side, after a single user search request.

    Could you please advice, what my next steps should be? Is there a filter or action I can use?

    You can certainly do that. You can use relevanssi_hits_filter hook. It gives you the search results to manipulate. If the array is empty, you take the search term (from $wp_query->query_vars['s']) and change it to the reverse layout, then run the search again with relevanssi_do_query($wp_query).
