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) AND suppress:false        1 résultat
• ((title:acceptabilité) OR (title:expropriation)) AND suppress: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

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
