With　the　development　of　healthcare　industry,　healthcare　informatization　provides　great　potential　for　the　health-care　improvement.　The　cloud　computing　platform,　which　is　an　important　infrastructure　for　the　inter(　intra)-organization　collaboration,　provides　a　shared　storage　space　to　the　medical　data　sharing.　For　the　privacy　protection　of　medical　data,　sensitive　data　has　to　be　encrypted　before　being　transmitted　to　the　cloud,　which　makes　it　more　challenging　to　use　these　data　in　the　cloud.　For　strengthening　the　utilization　of　encrypted　cloud　data,　various　encrypted　search　technologies　are　widely　studied.　However,　these　existing　searchable　encryption　schemes　may　not　enforce　users＇　demands　well.　This　paper　proposes　a　privacy　enhanced　search　approach　for　cloud-based　medical　data　sharing.　The　proposed　solution　implements　a　hybrid　search　approach,　where　the　search　process　is　conducted　across　plaintext　and　ciphertext.　Moreover,　the　enhanced　access　control　can　ensure　the　privacy　protection　of　cloud　data.　The　empirical　experiments　illustrate　the　effectiveness　of　our　solution.
