@ankur Prem I think I’ve got your point here , so let’s break it up :
1 – woocommerce search widget
The widget uses the wordpress functions to display products and that’s what allowed polylang to display the correct products according to active langauge , and that’s what we expect , so as you said It is OK
2 – Search By Product tag – for Woocommerce plugin
I’ve just installed the plugin and made some tests , as it seems the plugin is using its own query to achive its goal , here is a snippet :
$query = "
select p.ID as post_id from $wpdb->terms t
join $wpdb->term_taxonomy tt
on t.term_id = tt.term_id
join $wpdb->term_relationships tr
on tt.term_taxonomy_id = tr.term_taxonomy_id
join $wpdb->posts p
on p.ID = tr.object_id
join $wpdb->postmeta visibility
on p.ID = visibility.post_id
and visibility.meta_key = '_visibility'
and visibility.meta_value <> 'hidden'
";
thats make it impossible for polylang or WooPoly to to correct the results plus it does not provider any filter for its query to add support ,
But guess what I still have the solution but you have add a two or three lines to the plugin , here is the modified version :
<?php

?>
please note that I am not adding support for my plugin here but a support for polylang in general , maybe you can ask the plugin author to add support for polylang as it is really easy .
3 – user getting redirected for an english version
That is the default behavior for woocommerce when there is only one result for your search terms .
