Apache Solrで独自のフィールドを作成してドキュメントをアップロードするには？

Question

私はSolrで初めて遊んでいます。 Ubuntu Serverにインストールして実行し、exampledocsディレクトリにあるサンプルxmlドキュメントを投稿し、サンプルファイルにある "monitor"、 "apple"、 "Dell"などのキーワードを検索できました。

今、カスタムフィールドを持つ独自のドキュメントを追加します。私は自分のカスタムものとschema.xmlファイル内のフィールドを置き換え

<add><doc> 
    <field name="id">3007WFP</field> 
    <field name="name">Dell Widescreen UltraSharp 3007WFP</field> 
    <field name="manu">Dell, Inc.</field> 
    <field name="cat">electronics</field> 
    <field name="cat">monitor</field> 
    <field name="features">30" TFT active matrix LCD, 2560 x 1600, .25mm dot pitch, 700:1 contrast</field> 
    <field name="includes">USB cable</field> 
    <field name="weight">401.6</field> 
    <field name="price">2199</field> 
    <field name="popularity">6</field> 
    <field name="inStock">true</field> 
    <!-- Buffalo store --> 
    <field name="store">43.17614,-90.57341</field> 
</doc></add>

<fields> 
    <!-- Valid attributes for fields: 
    name: mandatory - the name for the field 
    type: mandatory - the name of a previously defined type from the 
     <types> section 
    indexed: true if this field should be indexed (searchable or sortable) 
    stored: true if this field should be retrievable 
    multiValued: true if this field may contain multiple values per document 
    omitNorms: (expert) set to true to omit the norms associated with 
     this field (this disables length normalization and index-time 
     boosting for the field, and saves some memory). Only full-text 
     fields or fields that need an index-time boost need norms. 
     Norms are omitted for primitive (non-analyzed) types by default. 
    termVectors: [false] set to true to store the term vector for a 
     given field. 
     When using MoreLikeThis, fields used for similarity should be 
     stored for best performance. 
    termPositions: Store position information with the term vector. 
     This will increase storage costs. 
    termOffsets: Store offset information with the term vector. This 
     will increase storage costs. 
    default: a value that should be used if no value is specified 
     when adding a document.

と

はこのdocという名前mydoc.xmlを投稿してみました

私は同じ古いコマンドを使用して投稿しようとしたとき：

java -jar post.jar mydoc.xml 

は、これは私が受信したエラーです：

SimplePostTool: version 1.4 
SimplePostTool: POSTing files to http://localhost:8983/solr/update.. 
SimplePostTool: POSTing file mydoc.xml 
SimplePostTool: FATAL: Solr returned an error #400 ERROR: [doc=null] unknown field 'user_id' 

私も、私はSolrのサービスを再起動する場合、それはSolrの管理者をロードするために失敗したことに気づきました、メッセージを与える：他のJavaタイプのエラーの束に続く

HTTP ERROR 500 

Problem accessing /solr/admin/. Reason: 

    Severe errors in solr configuration. 

Check your log files for more detailed information on what may be wrong. 

If you want solr to continue after configuration errors, change: 

<abortOnConfigurationError>false</abortOnConfigurationError> 

in solr.xml 

を...

schema.xmlから独自のカスタムフィールドを削除してSolrを再起動した場合、Solr Adminが正常にロードされます。

私はここで紛失しています。自分のカスタムフィールドを追加して、自分のドキュメントをSolrに投稿できるようにするにはどうすればいいですか？であることを

<uniqueKey>id</uniqueKey> 

：

<uniqueKey>user_id</uniqueKey> 

のschema.xmlの下部に

Answer 1

問題だった、私はこれを更新することを忘れていました。もう1つの問題は、Solrの管理者で*:*を使用して検索したときにすべて問題なく、文字列（キーワード）で検索したときにundefined field textというエラーが発生しました。これを修正するには、これを自分のフィールドの1つとして追加する必要がありました。

<field name="text" type="text_general" indexed="true" stored="false" multiValued="true"/>
