How to use the @ohif/core.studies function in @ohif/core

patientName: searchData.patientName,
      accessionNumber: searchData.accessionNumber,
      studyDescription: searchData.studyDescription,
      modalitiesInStudy: searchData.modalities,
      studyDateFrom: searchData.studyDateFrom,
      studyDateTo: searchData.studyDateTo,
      limit: searchData.rowsPerPage,
      offset: searchData.currentPage * searchData.rowsPerPage,
    };

    if (server.supportsFuzzyMatching) {
      filter.fuzzymatching = true;
    }

    // TODO: add sorting
    const promise = OHIF.studies.searchStudies(server, filter);

    this.setState({
      searchingStudies: true,
    });
    promise
      .then(studies => {
        if (!studies) {
          studies = [];
        }

        const { field, order } = searchData.sortData;
        let sortedStudies = studies.map(study => {
          if (!moment(study.studyDate, 'MMM DD, YYYY', true).isValid()) {
            study.studyDate = moment(study.studyDate, 'YYYYMMDD').format(
              'MMM DD, YYYY'
            );

queryFiltersArray.forEach(filter => {
    const searchStudiesPromise = OHIF.studies.searchStudies(server, filter);
    queryPromises.push(searchStudiesPromise);
  });
