0.5.0

PERFORMANCE! Loupe 0.5 now searches the 32k movies.json database for Amakin Dkywalker with typo tolerance enabled and ordered by relevance in about 80 ms 🚀
Faster State Set Index implementation (work happened in https://github.com/Toflar/state-set-index)
State Set is now added as PHP file on top for OPCache improvements when using persistance - this means that there is an API change for LoupeFactory::create() which now requires a directory instead of a database-only path!
Prefix search now with typo tolerance! This is not enabled by default because of performance reasons but you can do so using TypoTolerance::create()->withEnabledForPrefixSearch(true).
Faster language detection when limiting the languages using Configuration::create()->withLanguages(['en', 'de'])
Entire new documentation section about performance!
Additional micro optimizations
We now have a CHANGELOG.md so devs can see the major changes in every version very quickly

Both addDocuments() and addDocument() now return an IndexResult. This means that when there's an issue in a
document, addDocuments() now continues to index the rest of the documents and does not abort immediately anymore. IndexResult gives you access to the summary and individual exceptions of documents.
Added SearchParameters::getHash() to identify a search query to allow for customized caching.
Prefer the sqlite3 driver over pdo-sqlite for performance reasons.
Uses the connection to determine the SQLite version instead of a separate query (better performance)

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) 😎

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'])
;

Typo tolerance can now be disabled a lot easier:

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

An SQLite based, PHP-only fulltext search engine.

Loupe…

…only requires PHP and SQLite, you don't need anything else - no containers, no nothing
…is typo-tolerant (based on the State Set Index Algorithm and Levenshtein)
…supports phrase search using " quotation marks
…supports filtering (and ordering) on any attribute with any SQL-inspired filter statement
…supports filtering (and ordering) on Geo distance
…orders relevance based on a typical TF-IDF Cosine similarity algorithm
…auto-detects languages
…supports stemming
…is very easy to use
…is all-in-all just the easiest way to replace your good old SQL LIKE %...% queries with a way better search experience but without all the hassle of an additional service to manage. SQLite is everywhere and all it needs is your filesystem.
