Changelog

All notable changes to this project will be documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Removed

  • BREAKING: Removed has_paradedb_index class attribute. It had no effect on library behavior. Remove self.has_paradedb_index = true from your models.

Changed

  • BREAKING: near now uses a symmetric left_terms/right_terms API across the relation and Arel DSLs, and both operands now accept a string, ParadeDB.regex_term, or a mixed list of strings and regex terms

0.2.0 - 2026-03-13

Added

  • Rails 7.2 support and CI coverage
  • New search/query APIs: regex_phrase, phrase_prefix, parse, grouped aggregate_by, and ParadeDB::Query.regex
  • Expanded snippet support with with_snippets and with_snippet_positions
  • ParadeDB diagnostics helpers: paradedb_indexes, paradedb_index_segments, paradedb_verify_index, and paradedb_verify_all_indexes
  • Additional aggregation helpers: percentiles, histogram, date_histogram, top_hits, and filtered
  • Support for passing regexes into proximity queries using ParadeDB.regex_term

Changed

  • Fuzzy search controls are now flattened across the relation and Arel DSLs with direct distance, prefix, and transposition_cost_one options
  • matching_all and matching_any now accept explicit tokenizer: overrides
  • Runtime index validation now includes index-class discovery, drift checks, indexed-field validation, and model helpers for paradedb_index_classes, paradedb_indexed_fields, paradedb_key_field, and paradedb_index_name
  • Facet and aggregation APIs now support exact: controls for exact versus windowed execution
  • README, examples, and Arel documentation were expanded to cover the newer query, snippet, aggregation, and diagnostics APIs

Fixed

  • Search/runtime tokenizer handling now renders tokenizer SQL safely and validates unsupported tokenizer and facet combinations earlier

Removed

  • BREAKING: near_regex has been removed in favor of calling near with a regex argument using ParadeDB.regex_term

0.1.0 - 2026-02-07

Added

  • Initial rails-paradedb release.
  • ActiveRecord model integration with ParadeDB entrypoints: search, more_like_this, with_facets, facets, with_agg, and facets_agg
  • ActiveRecord relation search API with ParadeDB operators: matching_all, matching_any, excluding, phrase, fuzzy, regex, term, near, phrase_prefix, more_like_this, parse, match_all
  • exists, range, and term_set helpers across relation and Arel DSLs
  • with_score and with_snippet decorators
  • Highlighting expansion with with_snippets and with_snippet_positions
  • Faceting support: facets and with_facets
  • Named aggregation helpers: ParadeDB::Aggregations, facets_agg, with_agg, and aggregates
  • Arel integration with custom builder and visitor support
  • BM25 index DSL with multi-tokenizer field configs, per-field options, tokenizer aliases, and index_options
  • Migration helper support for creating/replacing/removing/reindexing BM25 indexes (create_paradedb_index, replace_paradedb_index, add_bm25_index, remove_bm25_index, and reindex_bm25)
  • Runtime safety checks for PostgreSQL adapter compatibility, index drift validation mode (:off, :warn, :raise), field-index validation, and class method collision detection
  • PostgreSQL adapter guards and integration test suite
  • Runnable examples for quickstart, faceted search, autocomplete, more-like-this, hybrid RRF, and RAG

Changed

  • with_agg/facets_agg now execute one pdb.agg(...) call per named aggregation to match ParadeDB aggregate parser constraints
  • README coverage was tightened for query and highlighting APIs

Fixed

  • Schema dump/load round-trip for tokenizer configuration and index options (including target_segment_count)
