如何在algolia中根据其类别筛选匹配点即时搜索

Question

我想根据其类别筛选匹配项，例如商店或咖啡。

这是我的查询：

searcher.setQuery(new Query().setGetRankingInfo(true).setAroundLatLng(new AbstractQuery.LatLng(12.670913552202967, 78.6066235229373)).setAroundRadius(1000)); 

如何过滤我得到的结果？

看看Algolia's Filtering Guide，你可以在这里了解过滤的工作原理。

随着Android客户端，您可以使用setFilters方法：

Query query = new Query("foo"); 
query.setFilters("category:coffee"); 

您可以找到client's documentation的更多信息：

/** 
* Filter the query with numeric, facet or/and tag filters. 
* <p> 
* The syntax is a SQL like syntax, you can use the OR and AND keywords. The syntax for the underlying numeric, facet and tag filters is the same than in the other filters: 
* {@code available=1 AND (category:Book OR NOT category:Ebook) AND _tags:public date: 1441745506 TO 1441755506 AND inStock > 0 AND author:"John Doe"} 
* 
* @param filters a string following the given syntax. 
* @return the {@link Query} for chaining.

public @NonNull Query setFilters(String filters)
