At a glance

Here are a few impressions on the way the library works:

$kwcmp = new Spekulatius\KeywordMerge\KeywordComparator;

$kwcmp->matchesWord('tbilisi georgia', 'is tbilisi the capital of georgia?');
// false

$kwcmp->containsWord('tbilisi georgia', 'is tbilisi the capital of georgia?');
// true

$kwcmp->similarWord('tbilisi georgia', 'georgias tbilisi');
// true

You call also use arrays with correlated methods:

$kwcmp = new Spekulatius\KeywordMerge\KeywordComparator;

$kwcmp->matchesWords('tbilisi georgia', 'is tbilisi the capital of georgia?');
// []

$kwcmp->containsWords('tbilisi georgia', 'is tbilisi the capital of georgia?');
// ['is tbilisi the capital of georgia?']

$kwcmp->similarWords('tbilisi georgia', 'georgias tbilisi');
// ['georgias tbilisi']

Keywords in URL Path

The library can also test for keywords in the URL path:

$kwcmp = new Spekulatius\KeywordMerge\KeywordComparator;

$kwcmp->inUrlPath('https://example.com/cats-are-awesome', 'seo tools');
// false

$kwcmp->inUrlPath('https://example.com/seo-tools', 'seo tools');
// true

$kwcmp->inUrlPath('https://example.com/chrome-seo-tools', 'chrome seo tools and toolkit');
// true - one word difference is accepted, from 3+ words

Further example and cases can be found in the tests!
