+#### Private Fields
+
+In certain scenarios, you may want to exclude specific fields from being matched unless explicitly specified. For example, without additional configuration, a query like `luxury` would match both the `name` and `description` fields:
+
+```typescript
+const data = [
+  { id: 2, name: 'Luxury Car Model AC', description: 'Car Model AC stands out with its unique features.', age: 15 },
+  { id: 3, name: 'Car Model AD', description: 'Experience the luxury of Car Model AD.', age: 30 },
+];
+```
+
+This package provides a method to ignore private fields by prefixing their names with an underscore and enabling the feature over a config. Private fields are excluded from wildcard matches but can still be explicitly queried when needed.
+
+```typescript
+const data = [
+  { id: 2, name: 'Luxury Car Model AC', _description: 'Car Model AC stands out with its unique features.', age: 15 },
+  { id: 3, name: 'Car Model AD', _description: 'Experience the luxury of Car Model AD.', age: 30 },
+];
+
+const $q = (q) => new QueryParser(q);
+
+filter($q('luxury'), data, {..., featureEnablePrivateField: true});
+filter($q('description:luxury'), data, {..., featureEnablePrivateField: true});
+```
+
+In this example, a generic query like `luxury` would only match the `name` field. However, if you need to target the private field, you can do so explicitly, such as with `description:luxury`.
