Show result in same tab (JSF)

Question

Hello, I have the following situation: I have a button (search) that executes a search method and returns the data in the same tab already opened in a <p:dataTable.

After generating a report on JasperReports (pdf button), which opens in a new tab , if I click the search button again, a new tab is also opened, and I would like the search to always be shown in the same tab. In the bean where are the methods below the scope is @ViewScoped. I would like help to understand this behavior and if possible adjust the code to open the search always in the same tab.

Method generating the report:

public void execute() throws ParseException {
        JasperReportBuilder report = DynamicReports.report();
        configure(report);
        String q = getQueryPrincipal(queryPrincipal)
                + getData(formatDataInicial(dataInicialQuery), formatDataFinal(dataFinalQuery));

        if (arrayCliente.size() > 0) {
            q = q + nomesParaQuery(queryNome);
        }
        if (arrayStatus.size() > 0) {
            q = q + statusParaQuery(queryStatus);
        }
        if (arrayOcorrencia.size() > 0) {
            q = q + ocorrenciasParaQuery(queryOcorrencia);
        }
        if (arrayFormasPg.size() > 0) {
            q = q + formasPgParaQuery(queryFormaPg);
        }
        if (arrayDespesa.size() > 0) {
            q = q + despesasParaQuery(queryDespesa);
        }

        report.setDataSource(q, con);
        System.out.println("Query: " + q);
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();

        try {
            response.setContentType("application/pdf");
            report.toPdf(response.getOutputStream());
            FacesContext.getCurrentInstance().responseComplete();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Research method:

public List<ConsultaEntrada> teste() throws SQLException, ParseException {
List<ConsultaEntrada> result = new ArrayList<ConsultaEntrada>();
String q = "";
try {
    System.out.println("ANTES:" + dataInicialQuery);
    System.out.println("ANTES:" + dataFinalQuery);
    // formatDataInicial(dataInicialQuery);
    // formatDataFinal(dataFinalQuery);
    System.out.println("Enviando:" + dataInicialQuery);
    q = getQueryPrincipal(queryPrincipal)
            + getData(formatDataInicial(dataInicialQuery), formatDataFinal(dataFinalQuery));
} catch (Exception e) {
    e.printStackTrace();

}
if (arrayCliente.size() > 0) {
    q = q + nomesParaQuery(queryNome);
}
if (arrayStatus.size() > 0) {
    q = q + statusParaQuery(queryStatus);
}
if (arrayOcorrencia.size() > 0) {
    q = q + ocorrenciasParaQuery(queryOcorrencia);
}
if (arrayFormasPg.size() > 0) {
    q = q + formasPgParaQuery(queryFormaPg);
}
if (arrayDespesa.size() > 0) {
    q = q + despesasParaQuery(queryDespesa);
}
Statement statement = con.createStatement();
ResultSet set = statement.executeQuery(q);

set.beforeFirst();
while (set.next()) {
    ConsultaEntrada consultaEntrada = new ConsultaEntrada();
    consultaEntrada.setCliente(set.getString("cliente_nome"));
    consultaEntrada.setOcorrencia(set.getString("ocorrencia_descricao"));
    consultaEntrada.setFormaPagamento(set.getString("entrada_acidente_forma_pagamento"));
    consultaEntrada.setStatus(set.getString("entrada_acidente_status"));
    consultaEntrada.setDataCriacao(set.getDate("entrada_acidente_data_criacao"));
    consultaEntrada.setDespesa(set.getString("despesa_nome"));
    result.add(consultaEntrada);
}
con.close();
return result;

}

public void pesquisar() throws ParseException {
    try {
        filtradas = teste();
        for (int i = 0; i < filtradas.size(); i++) {
        }
        System.out.println("Verificando tamanho lista" + filtradas.size());

    } catch (SQLException e) {

        e.printStackTrace();
    }
}
