如何在 solr 4 中导入和索引 mongodb 数据 [英] How to import and index mongodb data in solr 4
问题描述
我是 solr
和 mongodb
的新用户.我已经在 mongodb
中创建了数据库和集合.
I am new user to solr
and mongodb
. I have created the database and collection in mongodb
.
现在我想在 solr
中导入和索引 mongodb
集合,用于将在数据库中搜索大量数据的应用程序.我在互联网上搜索了很多,但没有得到满意的信息.谁能告诉如何使用步骤在 solr
中建立索引?
Now i want to import and index that mongodb
collection in solr
for the application which is going to search large amount of data in database. I have searched a lot on internet but,i did not got satisfactory information. Can anyone tell how to do indexing in solr
with steps ?
以下是我创建的集合:
db.stud.find().pretty()
{ "_id" : 1, "roll" : 59, "name" : "sachin", "class" : "MCA" }
{ "_id" : 2, "roll" : 57, "name" : "jay", "class" : "MCA" }
{ "_id" : 3, "roll" : 101, "name" : "akash", "class" : "BCA" }
{ "_id" : 4, "roll" : 11, "name" : "amit", "class" : "MCS" }
{ "_id" : 5, "roll" : 55, "name" : "shiv", "class" : "MCA" }
以下是我的data-config.xml文件,如果我做错了,请告诉我:
following is my data-config.xml file, please tell me if i have done any mistake:
<dataConfig>
<dataSource name="MyMongo" type="MongoDataSource" database="sachin" />
<document name="Products">
<entity processor="MongoEntityProcessor"
query="{'Active':1}"
collection="stud"
datasource="MyMongo"
transformer="MongoMapperTransformer" >
<field column="_id" name="_id" mongoField="_id"/>
<field column="roll" name="roll" mongoField="roll"/>
<field column="name" name="name" />
<field column="class" name="class" />
</entity>
</document>
</dataConfig>
我的数据库名称是sachin".
my database name is 'sachin'.
我对如何定义 schema.xml 文件以及我应该根据我的数据库架构修改它的哪些内容感到困惑.以下是我在 schema.xml 中所做的更改:
I am confused about how to define schema.xml file and what containts of it should i modify according to my database schema. Following are the changes i have done in schema.xml :
<uniqueKey>_id</uniqueKey>
<schema name="MongoEX" version="1.1">
<fields>
<field name="_id" type="string" indexed="true" stored="true" />
<field name="roll" type="sint" indexed="true" stored="true" />
<field name="name" type="string" indexed="true" stored="true" />
<field name="class" type="string" indexed="true" stored="true" />
</fields>
我在 solrconfig.xml 文件中所做的更改如下所示:
changes that i have made in solrconfig.xml file looks like following:
<lib dir="../../../../dist/" regex="solr-dataimporthandler-.*.jar" />
<lib dir="../../../dist/" regex="mongo-2.10.1.jar" />
<lib path="../../../dist/mongo-connector-1.1.1.jar"/>
<lib path="../../../dist/solr-dataimporthandler-4.4.0.jar"/>
<requestHandler name="/sqldataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">/home/ubuntucomp/Music/solr-4.4.0/example/example-DIH/solr/MongoEX /conf/data-config.xml</str>
</lst>
</requestHandler>
请告诉我我在上述所有文件中犯的任何错误,以便我可以索引 mongodb.
please, tell me whatever mistakes i have made in all above files, so that i can index mongodb.
先谢谢你..
推荐答案
您已经提到 query="{'Active':1}"
在stud 集合中没有具有字段名称的文档 <代码>活动代码>
You have mentioned query="{'Active':1}"
there is no document in stud collection with the field name Active
您可以按照步骤中提到的步骤操作使用 DataImportHandler
希望对您有所帮助.
