全文檢索中arangodb使用AQL和python

我已經存儲的數據中arangodb以下列格式：全文檢索中arangodb使用AQL和python

爲了執行全文搜索，我已經通過使用從語法創建的內容屬性的索引Python腳本：

c.DSP.ensureFulltextIndex("content");

其中，C爲數據庫，DSP是集名稱。現在，我想在上面的數據使用語法設置執行搜索操作：

FOR doc IN FULLTEXT(DSP, "content", "username") RETURN doc

然後，錯誤occure：

[1571] in function 'FULLTEXT()': no suitable fulltext index found for fulltext query on 'DSP' (while executing)

請告訴我問題，還告訴我當我用python腳本嘗試這個查詢時，語法是什麼。

謝謝...

你看看管理界面了嗎？ Collections-> yourCollection [（I）] - >索引 - 您應該在列表中找到您的索引。 – dothebart

謝謝dothebert，現在我已經通過arangodb界面創建了索引...但是上面的查詢返回空列表[]作爲結果.... –

如果我的眼球grep工作正常，你沒有任何'content'包含字符串'username'的屬性？請參閱[全文索引示例]（https://docs.arangodb.com/IndexHandling/Fulltext.html） – dothebart

與the 10 minutes tutorial工作和driver documentation

我得到它的工作是這樣的：

from pyArango.connection import * 
c = Connection() 
db = c.createDatabase(name = "testdb") 
DSP= db.createCollection(name = "DSP") 

DSP.ensureFulltextIndex(fields=["content"]) 

doc = DSP.createDocument({"content": "test bla"}) 
doc.save() 

print db.AQLQuery('''FOR doc IN FULLTEXT(DSP, "content", "bla") RETURN doc''', 10)

，導致：

[{u'_key': u'1241175138503', u'content': u'test bla', u'_rev': u'1241175138503', u'_id': u'DSP/1241175138503'}]

我用arangosh重新驗證pyt的步驟hon提示：

arangosh> db._useDatabase("testdb") 
arangosh [testdb]> db.DSP.getIndexes() 
[ 
    { 
    "id" : "DSP/0", 
    "type" : "primary", 
    "fields" : [ 
     "_key" 
    ], 
    "selectivityEstimate" : 1, 
    "unique" : true, 
    "sparse" : false 
    }, 
    { 
    "id" : "DSP/1241140928711", 
    "type" : "hash", 
    "fields" : [ 
     "content" 
    ], 
    "selectivityEstimate" : 1, 
    "unique" : false, 
    "sparse" : true 
    }, 
    { 
    "id" : "DSP/1241142960327", 
    "type" : "fulltext", 
    "fields" : [ 
     "content" 
    ], 
    "unique" : false, 
    "sparse" : true, 
    "minLength" : 2 
    } 
] 
arangosh [testdb]> db.testdb.toArray() 
[ 
    { 
    "content" : "test bla", 
    "_id" : "DSP/1241175138503", 
    "_rev" : "1241175138503", 
    "_key" : "1241175138503" 
    } 
] 
db._query('FOR doc IN FULLTEXT(DSP, "content", "bla") RETURN doc')

您好先生，我試過這個查詢 –

您是否重新驗證arangosh窗口的輸出？ – dothebart

是的，我已經重新驗證了我的輸出 –

全文檢索中arangodb使用AQL和python
