## What it is
Wukong is a highly customizable full-text search engine library written in Go, with efficient indexing, Chinese word segmentation via the sego package, BM25 scoring, and realtime index updates. It is embedded as a Go library rather than a standalone server, and supports persistent storage and distributed indexing.

## Use cases
- add full-text search to a Go application
- build a Chinese-language search engine
- index millions of documents quickly
- implement BM25 relevance ranking with custom scoring
- run realtime indexing with online add and delete
- build a distributed search cluster

## When to choose
- you need an embeddable Go search engine with strong Chinese tokenization
- you want custom scoring rules and token proximity ranking
- you need high-throughput indexing and low-latency search inside your own service

## When to avoid
- you need a turnkey standalone search server with REST API like Elasticsearch
- you need active maintenance and recent updates
- you need multilingual search beyond Chinese without extra work

## Facets
- artifact type: library

- function: search-engine, nlp
- domain: developer-tools
