    const CPosLmSearchCriteria &aCriteria,
    CPosLmMultiDbSortPref *aSortPref,
    TBoolaSearchOnlyPreviousMatches
    )[static]

    Two-phased constructor.

    Parameters

    CPosLmMultiDbSearch * aMultiDbSearchA pointer to the multi db search object.
    const CPosLmSearchCriteria & aCriteriaThe search criteria.
    CPosLmMultiDbSortPref * aSortPrefA pointer to the sort preference object. This class takes ownership.
    TBool aSearchOnlyPreviousMatchesThis flag may be used to perform a search within the results of previous search.

    NextStep(TRequestStatus &, TReal32 &)

    voidNextStep(TRequestStatus &aStatus,
    TReal32 &aProgress
    )[virtual]

    From CPosLmOperation.

    Performs one step of the operation asynchronously.

    Parameters

    TRequestStatus & aStatusThe request status. Will be completed when the step has been performed. The request status will be KRequestPending if the step has not completed. It will be KPosLmOperationNotComplete if the step has completed but more steps are needed before the operation has finished. The request status will be KErrNone if the operation has finished successfully.
    TReal32 & aProgressWill be set to the progress of the operation when the step has finished.

    OpenDbAndCreateInitOpL()
