I think your problem is related with the use of the operator argument in your tax_query. Actually you are using IN and NOT IN. From your question I understand you want AND. Also, you don’t need set terms aguments to 0 if the $_POST[] is not set: if(isset($_POST[‘fac’])) { // I assume that $_POST[‘fac’] is … Read more
Using pre_get_posts to filter by custom fields while using static front page

Based on my subsequent review of wp-includes/query.php, what I was attempting is simply not possible. This is because the query vars may only be modified to predefined set of values. As best I can determine, you cannot arbitrarily modify queries.
Your SQL dump proved to be informative.. Either 1=2 or 1=0 in a SQL statement means something you passed your WP_Query was invalid. It appears that in your tax_query you specified ‘field’=>’term_id’, which isn’t a valid option – it should be just ‘field’=>’id’.
