使用Solrj/Spring Data Solr实现标记和排除过滤器 [英] Implementing Tagging and Excluding Filters with Solrj / Spring Data Solr

问题描述

我正在尝试通过对字段进行多选来实现Solr Facet搜索.以该示例为例: http://docs.lucidworks.com/display/solr/Faceting#Faceting-LocalParametersforFaceting ，我想生成对solr的调用:

I am trying to implement a Solr Facet search with multi-select on a field. To take this example: http://docs.lucidworks.com/display/solr/Faceting#Faceting-LocalParametersforFaceting, I would like to generate this call to solr:

q=mainquery&fq=status:public&fq={!tag=dt}doctype:pdf&facet=on&facet.field={!ex=dt}doctype

我不确定如何使用solrj(java)调用此方法，因为我不想添加简单的文件，但是我需要包括标记和排除项(！tag = dt和！ex = dt).有什么想法Java代码应该是什么样的?

I am not sure how to call this using solrj (java) as I don't want to add a simple filed but I need to include the tagging and excluding (!tag=dt and !ex=dt). Any ideas what the java code should look like?

我正在使用Spring-Data-Solr，它似乎太基本了，无法进行这样的提前调用.所以我认为我需要降低一点并使用solrj.两种解决方案都很棒(solrj或spring-data-solr)

I am using Spring-Data-Solr which seems to be too basic to make such an advance call. So I think I need to go a level lower and use solrj. Either solution would be great (solrj or spring-data-solr)

推荐答案

以下代码段应创建所需的查询字符串.

The following block should create the querystring you want.

SimpleFacetQuery query = new SimpleFacetQuery(new SimpleStringCriteria("mainquery"))
  .addFilterQuery(new SimpleQuery(new Criteria("status").is("public")))
  .addFilterQuery(new SimpleQuery(new Criteria("{!tag=dt}doctype").is("pdf")));
query.setFacetOptions(new FacetOptions("{!ex=dt}doctype"));

solrTemplate.queryForFacetPage(query, YourBean.class);
