I've been reading the documentation and other example posts since yesterday to work out how to add sort by field and the direction to my current query array here but so far no luck. I've seen examples like {"sort": {"_score": "desc"}, "query": { .... but couldn't quiet get my head around it to modify my array since this is the very first time I'm dealing with ES.

All I need is: I want to be able to sort by price or stock in asc or desc order.

Everytime I try to update my array to implement sorting, I get {"error":{"code":0,"message":"Invalid option sort"}} error.

NOTE: The query array is being passed to Pagerfanta to get results.

    $paginator = $this->productFinder->findPaginated($myArray)


对于特定的字段和方向:</ p>

“sort”: {
</ code> </ pre>

对于没有特定的排序(这是设置的) 默认情况下):</ p>


</ code> </ pre>
</ div>



For the specific field and direction:

   "sort": {
      "price": "asc"
   ... rest of the code

For no particular sorting (this is set by default):

   "sort": {
      "_score": "desc"
   ... rest of the code

以下是一个示例:</ p>

“_source”:true,\ n“query”:{
“query”:“1 *”
“ 命令“:”desc“,
”缺少“:”_ last“
”缺少“:” _last“
</ code> </ pre>
</ div>



Here's an example:

ES 是否可以修改字段类型或者删除字段???

大佬们, ES有方法 可以修改字段类型或者删除字段吗?除了索引重建


<div class="post-text" itemprop="text"> <p>I'm using olivere's elastic v.5 Go library (<a href="https://godoc.org/gopkg.in/olivere/elastic.v5" rel="nofollow noreferrer">https://godoc.org/gopkg.in/olivere/elastic.v5</a>) for my Elastic queries.

Elasticsearch。 数据更新和保留以前字段值的历史记录

<div class="post-text" itemprop="text"> <p>Part of my mapping is:</p> <pre><code>"current_price" =&gt; ["type" =&gt; "float"], "price_history" =&gt; [ "type" =&gt; "nested", "properties" =&gt; [ "date" =&gt; ["type" =&gt; "date"], "value" =&gt; ["type" =&gt; "float"] ] </code></pre> <p>As you can see I keep in storage current price of goods and all the previous values. First thing I would like to notice is when I create goods in a very first time, I have no history, of course. That's why when I create goods, I do not use price_history at all, although it exists in my mapping.</p> <pre><code>$params = [ 'index' =&gt; config('storesettings.esIndex'), 'type' =&gt; config('storesettings.esType'), 'id' =&gt; $id, 'body' =&gt; [ ... "current_price" =&gt; $request-&gt;get('current_price'), ... ] ]; </code></pre> <p>When I edit goods, I change the price. In this case I need to move the current price to archive, moving it to price_history field. And then I need to replace current name. The question is about price_history field. I get previous value ($goods['_source']['price_history']) then I add to this array current_name. Everything is fine when I already have some history. But if I have not, then I get the error 'Undefined index: price_history'. In this case I should do checking: if(isset($goods['_source']['price_history'])). Is it normal? In relational databases I would have an empty array, but in Elasticsearch I haven't and I must do array level (so to speak) checking. How to handle such cases? Maby I should add an epmty array to price_history when I create goods?..</p> </div>


<div class="post-text" itemprop="text"> <p>I’m currently working on an app where we are handling events. So, in Elasticsearch, we do have a document named Event.</p> <p>Previously, we only had one kind of event (unique event happening the 13 May from 9 AM to 11 AM), the sorting was simple (sort by start_date with an order)</p> <p>We recently added a new feature that allows us to create recurring events, that means that we now have 2 levels inside Elasticsearch (parent-child relation).</p> <p>We can have a parent event that is from the 12 May from 2 PM to the 14 May from 6 PM, linked to that event, we have the children that are daily, for example. So we’d have: 12 May 2PM-6PM, 13 May 2PM-6PM, 14 May 2PM-6PM.</p> <p>The problem with the actual sort is that when we are the 12 May at 10 PM, we’ll find the recurring event on top of the list and after that, will come the unique event.</p> <p>I’d like to have a sorting where the nearest date has a higher priority. In that case, the unique event should have been the first on the list.</p> <p>To make that happen, I have indexed node children on recurring event parent, in order to have the children start_date. The idea would be to get the nearest date out of the children node for every recurring event and sort that one with the start_date of every unique event.</p> <p>I do not have a big experience with elasticsearch, so I’m kind of stuck, I saw a lot of information in the documentation (parent-child, nested objects, scripts, etc.) but I don’t know how to handle this case.</p> <p>I hope that I have explained myself correctly if you have any questions, feel free to ask them, I would be happy to provide you with additional information.</p> </div>

在上周,我密集面试了若干位Java后端的候选人,工作经验在3到5年间。我的标准其实不复杂:第一能干活,第二Java基础要好,第三最好熟悉些分布式框架,我相信其它公司招初级开发时,应该也照着这个标准来面的。 我也知道,不少候选人能力其实不差,但面试时没准备或不会说,这样的人可能在进团队干活后确实能达到期望,但可能就无法通过面试,但面试官总是只根据面试情况来判断。 但现实情况是,大多数人可能面试前没准备,或准备方法不得当。要知道,我们平时干活更偏重于业务,不可能大量接触到算法,数据结构,底层代码这类面试必问
