我正在使用rails和algolia gem以及mongoid数据存储区。
我正在向algolia发送数据Question
。 Algolia系统中的一个文档示例是
objectID: 5691e056410213a381000000
text: "what is #cool about your name Mr. John? #name #cool"
asked_to: ["565571704102139759000000", "i7683yiq7r8998778346q686", "kjgusa67g87y8e7qtwe87qwe898989"]
asked_by: "564a9b804102132465000000"
created_at: "2016-01-10T04:38:46.201Z"
card_url: "http://localhost:3000/cards/5691e056410213a381000000"
answerers: []
has_answer: false
requestor_count: 0
status: "active"
popularity_point: 0
created_at_i: 1452400726
_tags: ["cool", "name"]
我想找到符合以下两个条件的所有文件:
1)text
包含your name
2)asked_to
包含i7683yiq7r8998778346q686
我正在使用Twitter的typeahead
javascript库。我的UI实现algolia搜索的javascript如下:
<input class="typeahead ui-widget form-control input-md search-box tt-input" id="typeahead-algolia" placeholder="Search questions" spellcheck="false" type="text" autocomplete="off" dir="auto" style="position: relative; vertical-align: top;">
$(document).on('ready page:load', function () {
var client = algoliasearch("APPLICATION_ID", "SEARCH_KEY");
var index = client.initIndex('Question');
$('#typeahead-algolia').typeahead(
{
hint: false,
highlight: true,
minLength: 1
},
{
source: index.ttAdapter({hitsPerPage: 10}),
displayKey: 'text'
}
).on('keyup', this, function (event) {
if (event.keyCode == 13) {
$('#typeahead-algolia').typeahead('close');
window.location.href = "/?keyword="+encodeURIComponent($('#typeahead-algolia').val());
}
});
$('.typeahead').bind('typeahead:select', function(ev, suggestion) {
window.location.href = suggestion.card_url;
});
});
所以我的问题是:
此代码完美无缺。但是如何在上面的javascript中为asked_to contains i7683yiq7r8998778346q686
添加条件以过滤掉结果。
答案 0 :(得分:4)
您可以在查询的asked_to
属性中使用构面过滤器。
首先需要将属性asked_to
声明为索引设置中的分面属性,然后通过asked_to:i7683yiq7r8998778346q686
查询参数将facetFilters
作为构面过滤器传递给查询。 / p>
更改索引设置后,您可以更改源以添加facetFilters
参数:
$('#typeahead-algolia').typeahead(
{
hint: false,
highlight: true,
minLength: 1
},
{
source: index.ttAdapter({hitsPerPage: 10, facetFilters: "asked_to:i7683yiq7r8998778346q686"}),
displayKey: 'text'
}
).on('keyup', this, function (event) {
if (event.keyCode == 13) {
$('#typeahead-algolia').typeahead('close');
window.location.href = "/?keyword="+encodeURIComponent($('#typeahead-algolia').val());
}
});
