In my class, eslint is complaining Expected 'this' to be used by class method 'getUrlParams'

Here is my class:

class PostSearch extends React.Component {

  constructor(props) {

    super(props);

    this.getSearchResults();

  }



  getUrlParams(queryString) {

    const hashes = queryString.slice(queryString.indexOf('?') + 1).split('&');

    const params = {};



    hashes.forEach((hash) => {

      const [key, val] = hash.split('=');

      params[key] = decodeURIComponent(val);

    });



    return params;

  }



  getSearchResults() {

    const { terms, category } = this.getUrlParams(this.props.location.search);

    this.props.dispatch(Actions.fetchPostsSearchResults(terms, category));

  }



  render() {

    return (

      <div>

        <HorizontalLine />

        <div className=container>

          <Col md={9} xs={12}>

            <h1 className=aboutHeader>Test</h1>

          </Col>

          <Col md={3} xs={12}>

            <SideBar />

          </Col>

        </div>

      </div>

    );

  }

}

What is the best approach to solve this or refactor this component?
