Polylang support

Yeah, that is kinda a way, but not exactly. I thought of another way, for autocomplete at least. Since your plugin already offloads the polylang taxonomy correctly, I figured I can highjack the request. Can you validate on your end? For me it does seems to work.

Currently I am forcing lang type, but that can be gathered from current page. This logic / idea is based on algolia search index I tried to filter with.

What to you think? The template currently does work for us by default, because it searches with polylang overwriting for only current language (it has problems that we will have to remove paginations sice that poses an issue).

// Store the original send method
const originalSend = XMLHttpRequest.prototype.send;

// Replace with our proxy
XMLHttpRequest.prototype.send = function(body) {
  // Check if this is an Algolia request by examining the URL
  // 'this' refers to the XMLHttpRequest instance
  if (this._url && this._url.includes('algolia.net/1/indexes')) {
    // Parse the body
    let bodyData = JSON.parse(body);
    
    // Add your custom filter
    bodyData.filters = "taxonomies.language:CZ";
    
    // Replace with modified data
    body = JSON.stringify(bodyData);
  }
  
  // Call original send with our modified body
  return originalSend.call(this, body);
};

// Capture the URL when open is called
const originalOpen = XMLHttpRequest.prototype.open;
XMLHttpRequest.prototype.open = function(method, url) {
  this._url = url;
  return originalOpen.apply(this, arguments);
};
