 ### Querying Posts by Custom Fields (Meta)
 
-There are multiples possibilities to query posts by their custom fields (meta). Just use the `hasMeta()` scope under `Post` (actually for all models using the `HasMetaFields` trait) class:
+There are multiples possibilities to query posts by their custom fields (meta) by using scopes on a `Post` (or another other model which uses the `HasMetaFields` trait) class:
+
+To check if a meta key exists, use the `hasMeta()` scope:
+```
+// Finds a published post with a meta flag.
+$post = Post::published()->hasMeta('featured_article'); 
+```
+
+If you want to precisely match a meta-field, you can use the `hasMeta()` scope with a value.
 
 ```php
-// Using just one custom field
-$post = Post::published()->hasMeta('username', 'jgrossi')->first(); // setting key and value
-$post = Post::published()->hasMeta('username'); // setting just the key
+// Find a published post which matches both meta_key and meta_value.
+$post = Post::published()->hasMeta('username', 'jgrossi')->first();

+If you need to match a case-insensitive string, or match with wildcards, you can use the `hasMetaLike()` scope with a value. This uses an SQL `LIKE` operator, so use '%' as a wildcard operator.
+
+```php
+// Will match: 'J Grossi', 'J GROSSI', and 'j grossi'.
+$post = Post::published()->hasMetaLike('author', 'J GROSSI')->first();
+
+// Using % as a wildcard will match: 'J Grossi', 'J GROSSI', 'j grossi', 'Junior Grossi' etc.
+$post = Post::published()->hasMetaLike('author', 'J%GROSSI')->first();
+```

 ### Fields Aliases
 
 The `Post` class has support to "aliases", so if you check the `Post` class you should note some aliases defined in the static `$aliases` array, like `title` for `post_title` and `content` for `post_content`.
