fts is a full-text search package in pure Go.
While the goal is to build a search engine this project isn't designed for production uses.
Currently the following features are supported :
- Parsing XML Documents to a Document collection
- Index building at runtime
- Tokenization, Normalization and Stemming (Using Porter's Algorithm)
In the future the following features will be added :
- Support JSON and Text corpus.
- BoltDB for on-disk storage.
- Support index building concurrently and index compression.
- Support skip-pointer construction for posting lists.
- Support more tokenizers.
- Support boolean queries.
- Use Roaring Bitmaps for posting lists.
- Support ranking and term weighting (TFIDF).
While implementing and testing use the enwiki dataset.
