The original text also describes the deployment of SOLR, because I have already had an article before, so omit

Application design index structure for search forum posts:

Field	Description
Id	Post ID
User	Publish user name or UserID
Title	Title
Content	Content
Timestamp	Publication time
Text	Put the title and content here, and you can search for the content at the same time.

6. The index structure above tells SOLR to overwrite E:\apache-solr-1.3.0\example\solr\conf\scheam.xml with the following, (you can back up this file to see the official example later):

<?xml version= "1.0" encoding= "UTF-8"?> <schema name= "Example" version= "1.1" > <types> <fie Ldtype name= "string" class= "SOLR. Strfield ' sortmissinglast= true ' omitnorms= ' true '/> <fieldtype name= ' Sint ' Class= ' SOLR. Sortableintfield "sortmissinglast=" true "omitnorms=" true "/> <fieldtype name=" date "class=" SOLR.

7, restart Tomcat, and then manually create two XML data files in E:\apache-solr-1.3.0\example\exampledocs. Save As Demo-doc1.xml and Demo-doc2.xml, respectively:

<?xml version= "1.0" encoding= "UTF-8"?>  
<add>  
    <doc>  
        <field name= "id" >1</ field>  
        <field name= "user" >chenlb</field>  
        <field name= "title" >SOLR Application speech </field>  
        <field name= "Content" > This section is about submitting data to the server to index, here are some data, such as: server, you can try to find it. </field>  
    </doc>  

<?xml version= "1.0" encoding= "UTF-8"?>  
<add>  
    <doc>  
        <field name= "id" >2</ field>  
        <field name= "user" >bory.chan</field>  
        <field name= "title" > Search engine </field>  
        <field name= "Content" > Search server There is a lot of data. </field>  
        <field name= "timestamp" >2009-02-18T00:00:00Z</field>  
    </doc>  
    < doc>  
        <field name= "id" >3</field>  
        <field name= "user" >other</field>  
        < Field name= "title" > What is this </field>  
        <field name= "Content" > What sports do you like? Basketball. </field>  
        <field name= "timestamp" >2009-02-18T12:33:05.123Z</field>  
    </doc>  

8, submit data to do index, to E:\apache-solr-1.3.0\example\exampledocs, run:

E:\apache-solr-1.3.0\example\exampledocs>java-durl=http://localhost:8080/solr/update-dcommit=yes-jar Post.jar demo-doc*.xml

This is the problem with SOLR 1.4 running this example. Error: Org.apache.solr.common.SolrException:QueryElevationComponent requires the schema to have a Uniquekeyfield Implemented using Strfield.

Remove two nodes from the Solrconfig.xml: the elevator component.

<searchcomponent name= "Elevator" class= "SOLR." Queryelevationcomponent ">
    <!--pick a fieldtype to analyze queries--> <str name=
   " Queryfieldtype "& gt;string</str>
    <str name= "Config-file" >elevate.xml</str>
  </searchComponent>

  <!--A Request handler for demonstrating the elevator component--> <requesthandler name=
