# Accessors
**Accessors** are used to manage state and produce a fragment of an ElasticSearch query. This seperates all the query + state logic away from Searchkit Components. Accessors also hold a key which is used to serialize/deserialize to the browser url. **Searchkit** manages this complexity in the background for you.

## Example usage
```js
let accessor = new PaginationAccessor("p")
accessor.state = accessor.state.setValue(5)
//...when searching
// url serializes to ?p=5
// from field gets added to Elastic Query
```
