            Bug ID: 27597
           Summary: Searching "kw:term" does not work with Elasticsearch
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5 - low
         Component: Searching - Elasticsearch
          Assignee: koha-bugs at lists.koha-community.org

In Koha/SearchEngine/Elasticsearch/QueryBuilder.pm :

There is a map of convertion from CCL :

our %index_field_convert = (
    'kw' => '',
    'ab' => 'abstract',
    'au' => 'author',
...

You see that kw is replaced by empty.

See that in _convert_index_strings() :

        my ($conv) = $self->_convert_index_fields($field);
        unless ( defined($conv) ) {
            push @res, $s;
            next;
        }
        push @res, ($conv->{field} ? $conv->{field} . ':' : '')
            . $self->_modify_string_by_type( %$conv, operand => $term );

If Field is empty the character ":" is not added.

This behavior is missing from _convert_index_strings_freeform() :

    $search =~ s/($field_name_pattern)($multi_field_pattern):/(exists
$index_field_convert{$1} ? $index_field_convert{$1} : $1)."$2:"/oge;

Query "kw:term" will be converted to ":term" :(
