Lucy::...DQuery(3pm)

💖 Lucy::Search::ANDQuery 💖

okay bestie, so this page is from the User Contributed Perl Documentation section of the manual, and it's all about Lucy::Search::ANDQuery — the iconic little composite query that only vibes with you when every single one of its children vibes too. it's giving "all my friends have to like you or it's a no" energy. 💅

---

✨ NAME ✨

Lucy::Search::ANDQuery — intersect multiple result sets, periodt. 💖

---

🌸 SYNOPSIS 🌸

my $foo_and_bar_query = Lucy::Search::ANDQuery->new(
    children => [ $foo_query, $bar_query ],
);
my $hits = $searcher->hits( query => $foo_and_bar_query );
...

like… look at her. she's building a query, handing it to the searcher, getting hits. ate and left no crumbs. 🎀

🦋 DESCRIPTION 🦋

so ANDQuery is a composite Query, meaning it's made of other queries (her children, her little squad 🫶). she matches only when all of her children match — so her result set is literally the intersection of their result sets. no stragglers, no half-matches, it's all-or-nothing bestie. 💀

and the docs that do match? they receive a summed score. all the children's scores get added up. math but make it cute. ⭐

👑 CONSTRUCTORS 👑

🌈 new 🌈

my $foo_and_bar_query = Lucy::Search::ANDQuery->new(
    children => [ $foo_query, $bar_query ],
);

creates a brand new ANDQuery, fresh out of the box, main character energy only. ✨

• children — an array of child Queries. that's it, that's the whole thing. your little query babies. 🍓

💅 METHODS 💅

🧚 make_compiler 🧚

my $compiler = $and_query->make_compiler(
    searcher    => $searcher,     # required
    boost       => $boost,        # required
    subordinate => $subordinate,  # default: false
);

an abstract factory method that returns a Compiler derived from this Query. fancy. 💜

• searcher — a Searcher. required, no cap. 🔥
• boost — a scoring multiplier. also required. 💖
• subordinate — tells you whether the Query is a subquery (as opposed to a top-level query). if it's false, the implementation must invoke normalize() on the newly minted Compiler object before returning it. yes, that's a must-must, not a suggestion. 🙈

🎀 INHERITANCE 🎀

Lucy::Search::ANDQuery isa Lucy::Search::PolyQuery isa Lucy::Search::Query isa Clownfish::Obj.

the whole family tree, glowing, iconic, slaying. 👑

okay that's the whole page bestie!! this one came from perl v5.42.0, dated 2025-07-25, and honestly? she's a classic. go forth and intersect your result sets. 💖✨🦋
