v0.1.2

• adhara.path() falls back to the extension module's __spec__.origin when the module has no __file__. A py2app bundle, such as the Leela app, imports the extension that way. Before, adhara.load() raised AttributeError there, and litesearch searched in Python.

Full Changelog: v0.1.1...v0.1.2

v0.1.1

• A filter is checked one window of candidates at a time, with the candidates looked up by rowid (VALUES with CROSS JOIN). A filter with an indexed subquery, such as vishalakshi's document-kind filter, no longer costs a scan of the rows it selects for each window.
• A window over 1/128 of the rows (at least 1,024) reads every passing rowid once and checks the rest in memory.
• The HNSW index file is read the first time a search uses it, not each time the vectors are read. litesearch passes ann=0 and never reads it.

v0.1.0

The first release of adhara, the SQLite core of litesearch.

• porter adhara, an FTS5 tokenizer with the tokens of litesearch's chain porter simplify casefold 1 sanskrit unicodewords.
• adhara_hybrid(store, q, qvec, k, filter, dtype, metric, ann), a full-text search, a vector search and Reciprocal Rank Fusion in one SQL call. It returns the rows of litesearch's search in the same order.
• Python: pip install adhara, then adhara.load(conn) on an apsw or sqlite3 connection.
• Swift: .package(url: "https://github.com/vedicreader/adhara", from: "0.1.0"). The package downloads AdharaCore.xcframework.zip from this release. It runs on macOS 13 and later, on Apple silicon and Intel, and reads stores that litesearch built in Python.
