NAME

6       Lucy::Search::RequiredOptionalQuery - Join results for two Queries, one
7       required, one optional.
8

SYNOPSIS

10           my $foo_and_maybe_bar = Lucy::Search::RequiredOptionalQuery->new(
11               required_query => $foo_query,
12               optional_query => $bar_query,
13           );
14           my $hits = $searcher->hits( query => $foo_and_maybe_bar );
15           ...
16

DESCRIPTION

18       RequiredOptionalQuery joins the result sets of one Query which MUST
19       match, and one Query which SHOULD match.  When only the required Query
20       matches, its score is passed along; when both match, the scores are
21       summed.
22

CONSTRUCTORS

24   new
25           my $reqopt_query = Lucy::Search::RequiredOptionalQuery->new(
26               required_query => $foo_query,    # required
27               optional_query => $bar_query,    # required
28           );
29
30       Create a new RequiredOptionalQuery.
31
32       ·   required_query - Query must must match.
33
34       ·   optional_query - Query which should match.
35

METHODS

37   get_required_query
38           my $query = $required_optional_query->get_required_query();
39
40       Getter for the required Query.
41
42   set_required_query
43           $required_optional_query->set_required_query($required_query);
44
45       Setter for the required Query.
46
47   get_optional_query
48           my $query = $required_optional_query->get_optional_query();
49
50       Getter for the optional Query.
51
52   set_optional_query
53           $required_optional_query->set_optional_query($optional_query);
54
55       Setter for the optional Query.
56
57   make_compiler
58           my $compiler = $required_optional_query->make_compiler(
59               searcher    => $searcher,     # required
60               boost       => $boost,        # required
61               subordinate => $subordinate,  # default: false
62           );
63
64       Abstract factory method returning a Compiler derived from this Query.
65
66       ·   searcher - A Searcher.
67
68       ·   boost - A scoring multiplier.
69
70       ·   subordinate - Indicates whether the Query is a subquery (as opposed
71           to a top-level query).  If false, the implementation must invoke
72           normalize() on the newly minted Compiler object before returning
73           it.
