Ever wanted to have random items put into the search results pulled from I18N Search?
It's actually not that difficult. The technique hinges on the return_i18n_search_results function, specifically designed for doing custom results rendering.
We call the function with the desired paramters to get the results. To ensure a properly random selection, we'll set the maximum number of results to a high number (e.g. 999).
$search = return_i18n_search_results($tags, $words, 0, 999, $order, $lang);
