如何通过Go中的REST通过查询查找节点

Question

I test find node by query refer to neo4j manual（http://docs.neo4j.org/chunked/snapshot/rest-api-indexes.html<22.10.10. Find node by query>, but I have some troubles, I created two nodes, one index. Then I add two nodes into index. I can't find anything when I query node by lucene query.

This is my test code：

func TestFindNodeByQuery(t *testing.T) {
    log.Println("Start testing FindNodeByQuery")
    session, err := Dial(settingFile)
    if err != nil {
        t.Error(err)
    }
    log.Println("Create Index,type lucene")
    indexName := "testIndex"
    indexType := "fulltext"
    indexProvider := "lucene"
    err = session.CreateNodeIndexWithConf(indexName, indexType, indexProvider)
    if err != nil {
        t.Error(err)
    }
    log.Println("create two nodes")
    data := map[string]string{
        "name":  "test01",
        "key01": "value01",
    }
    node1, err := session.CreateNode(data)
    if err != nil {
        t.Error(err)
    }
    data["name"] = "test02"
    node2, err := session.CreateNode(data)
    if err != nil {
        t.Error(err)
    }
    indexKey := "some key"
    indexValue := "some value"
    _, err = session.AddNodeToIndex(indexKey, indexValue, indexName, node1.ID)
    if err != nil {
        t.Error(err)
    }
    _, err = session.AddNodeToIndex(indexKey, indexValue, indexName, node2.ID)
    if err != nil {
        t.Error(err)
    }
    luceneQuery := "indexKey:some*"
    results, err := session.FindNodeByQuery(indexName, luceneQuery)
    // results, err := session.FindNodeByMatch(indexName, indexKey, indexValue)
    log.Println(len(results))
    for _, result := range results {
        log.Println(result)
    }
    log.Println("Clean data...")
    err = session.DeleteNode(node1.ID)
    if err != nil {
        t.Error(err)
    }
    err = session.DeleteNode(node2.ID)
    if err != nil {
        t.Error(err)
    }
    err = session.DeleteNodeIndex(indexName)
    if err != nil {
        t.Error(err)
    }
    log.Println("data cleaned")
    log.Println("FindNodeByQuery test finished!")

}

Try to use an index key without spaces. That makes your live easier.

Then you actually have to use the correct index key that you stored data under in your lucene query:

luceneQuery := "some_key:some*"

if you used

indexKey := "some_key"

before. Not as you did: luceneQuery := "indexKey:some*"
