SOLR排序不起作用

Question

向SOLR查詢添加排序條件。首先按照department_sortable和productname_sortable進行排序。按照department_sortable排序，但不按productname_sortable排序。

private List<SortField> getSortParameters() { 
List<SortField> sortFields = new ArrayList<SortField>(); 
sortFields.add(generateSortField("department_sortable", SortDirection.ASC)); 
sortFields.add(generateSortField("productname_sortable", SortDirection.ASC)); 
return sortFields; 
} 


<field name="productname_sortable" type="text" indexed="true" stored="false" /> 
<field name="department_sortable" type="string" indexed="true" stored="false" multiValued="false"/> 


<copyField source="productname" dest="productname_sortable"/> 
<copyField source="department" dest="department_sortable"/> 

Answer 1

我認爲，只有一個排序字段設置爲solrQuery。您可以通過使用SolrQuery#addSortFieldMethod

solrQuery.addSortField("department_sortable", org.apache.solr.client.solrj.SolrQuery.ORDER.asc); 
solrQuery.addSortField("productname_sortable",org.apache.solr.client.solrj.SolrQuery.ORDER.asc); 

或

solrQuery.addOrUpdateSort("department_sortable", org.apache.solr.client.solrj.SolrQuery.ORDER.asc);

Answer 2

嘗試

`solrQuery.setSort(new SortClause("department_sortable", "asc")); 
solrQuery.setSort(new SortClause("productname_sortable", "asc"));` 

或

`solrQuery.setSort(new SortClause("department_sortable", "asc")); 
solrQuery.addSortField(new SortClause("productname_sortable", "asc"));` 

或 solrQuery.setSort(new SortClause("department_sortable", "asc")); solrQuery.addSortField("productname_sortable", "asc");
