v1.1.1

This release adds handling for the apostrophe character (') in search terms.

v1.1.0

This release adds improved handling of special characters in both the PostgreSQL and SQLite backends. Search terms with hyphens are now fully supported. The wildcard * at the end of a word is supported in both backends. Wildcards at the beginning of a word are not supported, but are handled gracefully (i.e. do not throw an error but simply ignore the wildcard) now.

v1.0.0

This release turns Sifts into a full-blown vector-embedding database for semantic search & LLM chat apps!

It makes use of the official PostgreSQL pgvector extension, but also works with the SQLite backend. You can choose to use full-text search, vector search, or both in the same collection.
