Hi Kevin, You were right, one of the indexed record was "hidden" so the second result was correct (24 Acceptabilité + 1 Expropriation).  I skipped it thinking the 25 was actually just 25 "acceptabilité" returned. Now, writting the query differently does it. * (title:acceptabilité) OR (title:expropriation) ANDsuppress:false        1 résultat * ((title:acceptabilité) OR (title:expropriation)) ANDsuppress:false      25 résultats But it's not what Koha is doing.  Can I interpret that this is a bug I should open and provide a fix for ? Thanks a lot, Philippe On 2022-02-18 09:33, Kevin Carnes wrote:

Hi Philippe,

Your second query appears to be correct. Is it possible that one of the "expropriation" records is suppressed in the the OPAC? Try searching for "title:expropriation AND suppress:true" (without QueryAutoTruncate).

It's possible to automatically add parentheses to both the query and the limits by editing the Koha/SearchEngine/Elasticsearch/QueryBuilder.pm file. After "$search_param_query_str = join( ' ', $self->_create_query_string(@search_params) );" add:         if ($search_param_query_str) {             $search_param_query_str = "($search_param_query_str)";         }         my $search_param_limits_str = $self->_join_queries( $self->_convert_index_strings(@$limits) );         if ($search_param_limits_str) {             $search_param_limits_str = "($search_param_limits_str)";         }

And then change the "$query_str" to:         $query_str = join( ' AND ',             $search_param_query_str || (),             $search_param_limits_str || () );

Hopefully that will produce the correct results.

Regards, Kevin
