Shallow routing Nextjs, undocumented case

shallow-routing-snippet

this.props.router.push(
		`/search?type=${this.state.type}&cat=${this.state.cat}&area=${this.state.area.name}&page=${currentQuery.page}&aid=${this.state.area.id}`,
		`/search/${this.state.type}/${this.state.cat}/${this.state.area.name}?page=${currentQuery.page}&aid=${this.state.area.id}`,
		{ shallow: true }
);

export default withRouter(connect(mapStateToProps)(SearchPage));

might also need this on your custom server:

  server.get('/search/:type/:cat/:area', (req, res) => {
    return app.render(req, res, '/search', {
      ...req.params,
      ...req.query,
    });
  });
