💖 Plucen...nalyzer(3pm) — the manual page, but make it make sense 💖

okay bestie, sit down, hydrate, and let's talk about Plucene::Analysis::Analyzer, which lives in the Perl User Contributed Perl Documentation section of your friendly neighbourhood 3pm man pages. she's a base class. she's abstract. she's the blueprint, not the building. let's get into it ✨

---

🌸 NAME 🌸

Plucene::Analysis::Analyzer — the base class for Analyzers. that's it, that's the whole name. lowkey iconic that it says exactly what it is.

---

🦋 SYNOPSIS 🦋

my $analyzer = Plucene::Analysis::Analyzer::Subclass->new;

yeah so you don't actually instantiate this one, bestie. you go through a subclass. the ::Subclass part is doing a lot of heavy lifting there, and we love her for it 💅

---

🎀 DESCRIPTION 🎀

this is an abstract base class of Analyzers. so like, she's the vibe, the template, the "you know what to do, go do it" energy. she does not do the thing herself. that's the point. 🙈

an Analyzer builds TokenStreams, which analyze text. so basically an Analyzer = a policy for extracting index terms from text. it's giving "I set the rules, the TokenStream does the cardio." 👑

typical implementations work in two lil stages, and it's a whole pipeline moment:

1. first they build a Tokenizer, which breaks the stream of characters coming from the Reader into raw Tokens. chop chop, break it down. 🍓
2. then one or more TokenFilters may be applied to the output of the Tokenizer. glow-up round, applied to the tokens, one or more of them. no cap.

---

✨ METHODS ✨

💜 new

my $analyzer = Plucene::Analysis::Analyzer::Subclass->new;

the constructor. again: subclass. she's abstract, remember. don't come for the base class expecting a whole object, she will not deliver that for you 😭

🌈 tokenstream

this one must be defined in a subclass.

like. must. it's not optional, it's not "eh we'll figure it out", it is a requirement, and if you skip it you're on your own fr fr. define it in your subclass. periodt. 🫶

---

real talk: because Plucene::Analysis::Analyzer is abstract, you never use it directly — you subclass it, you give it a tokenstream, and then you have an Analyzer. that's the whole arc of this man page. 💖

---

and that's the page, bestie!! 🎀 this one came out of the Perl User Contributed Perl Documentation, straight off perl v5.36.0, dated 2022-12-04, and the header was Plucen...nalyzer(3pm) (yes the title is literally truncated like that, we don't make the rules, we just analyze text 💅). go forth and build your TokenStreams, mwah 😘💖✨
