有没有一种方法在hibernate-search中查找搜索词的字段？ [英] Is there a way in hibernate-search to facet by fields where the search term was found?

问题描述

考虑以下索引实体：

  @Entity 
 @Indexed 
 public class Document {
 
 ... 
 
 @Field 
私有字符串标题; 
 
 @Field 
 private String text; 
 
 
 $ / code> 

有没有办法向用户展示一个包含两个选项标题和文本以及在标题中找到搜索词的文档计数和文字分别？用户应该能够选择这些选项，以便只搜索有趣的字段。

例如，有三个文件：

  {title：One，text：One} 
 {title：One and Two，text： Two} 
 {title：Three，text：Three and Two} 
  

而搜索查询是one：那么方面将是：

  {title： 2，text：1} 
  

解决方案

这种内置的功能在Hibernate Search中，但你可以自己做。而不是运行一个查询，运行三个：

1. 一个带有标题或文本筛选器，不需要分面


2. 其中一个仅在标题字段中显示过滤器，并且只在文本字段中显示title字段
   
3. 然后从第一个查询中收集结果，第二个查询中的标题方面以及第二个查询中的标题方面第三个查询中的文本方面。

   Consider the following indexed entity:

   @Entity
   @Indexed
   public class Document {
   
       ...
   
       @Field
       private String title;
   
       @Field
       private String text;
   
   }
   

   Is there a way to present user a facet that will contain two options title and text with a count of documents where the search term was found in title and text respectively? And the user should be able to select these options to search only by interesting fields.

   For example, there are three documents:

   { "title" : "One", "text" : "One" }
   { "title" : "One and Two", "text" : "Two" }
   { "title" : "Three", "text" : "Three and Two" }
   

   And the search query is "one": then the facet will be:

   { "title" : 2, "text" : 1 }
   

   解决方案

   There is no such built-in feature in Hibernate Search, but you can do it yourself. Instead of running a single query, run three:

   1. one with a filter on "title OR text", without faceting
   2. one with a filter only on the "title" field, with faceting on the "title" field
   3. one with a filter only on the "text" field, with faceting on the "text" field

   Then gather the results from the first query, the "title" facet from the second query, and the "text" facet from the third query.
