我試圖使用Spring Data Solr查詢來自後端Solr服務器的東西，它具有以下schema.xml（顯示您只是字段爲簡單起見），它是從Nutch schema.xml複製的。這意味着，我已經爬到使用Nutch的網頁，然後通過細分到Solr：Solr字段在Spring Data Solr中如何映射？

現在，看着春數據Solr的文檔，例如這裏：
http://docs.spring.io/spring-data/solr/docs/1.4.x/reference/html/#reference
他們使用的方法和字段似乎與我的模式中的字段不匹配。例如，在文檔它們有：
public interface ProductRepository extends Repository<Product, String> {
List<Product> findByNameAndPopularity(String name, Integer popularity);
}
或
public interface ProductRepository extends SolrRepository<Product, String> {
@Query("inStock:?0")
List<Product> findByAvailable(Boolean available);
}
而且在看我的領域我沒有任何所謂的「名」，「人氣」或「可用」的字段。我錯過了什麼？我應該改變我的模式嗎？我應該從文檔更改存儲庫嗎？
這最後一個問題看起來很愚蠢，但由於我見過的使用Spring Data Solr的示例僅創建Product模型（我知道它是一個示例，但示例通常反映了默認情況！）以及它們相應的Solr存儲庫，通常包含諸如「名稱」，「流行度」，「作者」等字段，我不確定這些字段實際代表或映射到的是什麼。
