注：skip和limit還可以做分頁查詢
public KgSearchResult getAutoQueryResultByKeyword(String sourceNodeId,String keyWord,Integer pageNo, Integer pageSize,boolean absolute) throws Exception {

//首先精確查詢節點，如只有一個，查詢返回；多個查詢後合併
String querySql = " match (sourceNode) where sourceNode.name ={objName} return sourceNode skip "+skipNum+" limit " +pageSize;
Map<String, Object> paraMap = new HashMap<>();
paraMap.put("objName",keyWord);
Result result = getDriver().session().run(querySql,paraMap);
List<Record> list = result.list() ;
if(null != result && list.size() == 1){//只有一條
kgSearchResult = getQueryResultById(""+getNodeId(list.get(0).asMap().get("sourceNode")),pageNo,pageSize);//根據nodeid查詢結果
}else if(null != result && list.size() > 1){//查出多條，合併
List<KgSearchResult> results = new ArrayList<>();
for (int i = 0; i < list.size(); i++) {

}
