[英]How to request facets from AWS CloudSearch via the PHP v2 SDK?
I am using v2 of the PHP SDK for interfacing requests to AWS CloudSearch.我正在使用 PHP SDK 的 v2 将请求连接到 AWS CloudSearch。 T he documentation is here , however details and examples are somewhat lacking.
文档在这里,但是细节和示例有些缺乏。 I need to include facets in my search.
我需要在我的搜索中包括方面。 It is clearly asking for a string but it is not clear exactly how the string should be formatted.
它显然要求一个字符串,但不清楚该字符串的确切格式。
$cloudSearchDomainClient->serach([
'filterQuery' => $filter,
'query' => $query,
'queryParser' => 'lucene',
'facet' => '???'
]);
I have tried, for example:我试过,例如:
'facet' => 'field1,field2,field3'
'facet' => 'facet.fieldname={sort:'count',size:5}'
'facet' => 'fieldname={sort:'count',size:5}'
(Some permutations based on examples in the non-sdk request descriptions here ) (基于此处非 sdk 请求描述中的示例的一些排列)
The appropriate syntax appears to be a string representing a javascript object.适当的语法似乎是表示 javascript 对象的字符串。
For the default sort/count:对于默认排序/计数:
'facet' => '{fieldname:{}}'
To specify sorting options:要指定排序选项:
'faceet' => '{fieldname:{'sort':'count',size:5}}'
To request multiple facets:要请求多个方面:
'facet' => '{field1:{},field2"{}}"
Etc.等等。
