0.3.0

Version 0.3.0 🥳

New features

• Entirely new language detection algorithm. Supported languages for detection can now be configured:

  $configuration = Configuration::create()
      ->withLanguages(['en', 'fr', 'de'])
  ;

• Documented Tokenizer internals

• Massively improved indexing performance. Based on the MeiliSearch 32k movies database we started out at about 15min (~35 documents per second) on version 0.2. Version 0.3 completes in less than 4min (~140 documents per second) 😎

0.2.0

Version 0.2.0 🥳

New features

• Added support for deleting documents:

  $loupe->deleteDocuments();
  $loupe->deleteDocument();

• Better performance and the docs now contain a section about what you can expect from Loupe.

• Added support for the != operator

• Added support for the IS NULL and IS NOT NULL operator

• Added support for the IS EMPTY and IS NOT EMPTY operator

• All operators now also work on multi value attributes. So you can search attributes like departments = ['foo', 'bar'] using =, !=, >= etc.

• Added better logging. All SQL queries are now logged so you know exactly what's going on in Loupe.

• You can now only search for a subset of the searchable attributes:

  $searchParameters = SearchParameters::create()
      ->withAttributesToSearchOn(['firstname'])
  ;

• You can now ask Loupe for the ranking score which will be a _rankingScore attribute on every hit:

  $searchParameters = SearchParameters::create()
      ->withShowRankingScore(true)
  ;

• Typo tolerance can now be disabled a lot easier:

  $configuration = Configuration::create()
      ->withTypoTolerance(TypoTolerance::disabled())
  ;

• Improved code quality. Loupe is now tested against PHPStan Level 8

• Reworked and documented document schema

Bugfixes

• Fixed issue with negative search on multi value attributes
• Fixed adding new attributes to an existing schema was not possible
• Lots of fixes regarding filtering and sorting null values
