Solr-查询中的多个facet.field

Question

I would like to add multiple facet.field (and also facet.count and other properties) to my Map to be used in SolrParams in a query but it only let you add one value per key (Java Map).

Can this be done?

Something like:

Map params = new Map();
params.put("facet.field", "title");
params.put("facet.field", "tags");
...
query(new SolrParams(params));

Answer 1

try this way

solrQuery.addFacetField(“subcat”)
solrQuery.addFacetField(“tags”)
solrQuery.addFacetField(“languages”)
