Solr 支持的标签云
我似乎陷入了 Solr 分面支持的标签云的逻辑背后。首先，我使用 OpenNLP 解析我的文档并从中获取相关单词，因此每个文档都被分成 n 个单词。 这基本上就是我的 Solr 响应的样子：
<docID>
<title>My Doc Title</title>
<content>My Doc Title</content>
<date_published>My Doc Title</date_published>
</docID>
我相信一定有一种方法可以将这些单词整合到这里。我首先想到的是这样的：
<docID>
<title>My Doc Title</title>
<content>My Doc Title</content>
<date_published>My Doc Title</date_published>
<words>word</words>
<words1>word1</words1>
<words2>word2</words2>
<words3>word3</words3>
<wordsN>wordN</wordsN>
</docID>
但是分面是不可能的，因为我不知道每个 docID 会得到多少个单词字段，那么分面必须跨字段完成（我什至不确定）这是可能的）。我正在尝试寻找可能的答案，但我似乎陷入了困境......最后，我需要对 n 个单词进行分面，以获取索引中的每个文档。非常感谢您的想法。
I seem to be stuck behind the logic of a Solr faceting-powered tag cloud. First of all, I'm using OpenNLP to parse my docs and obtain relevant words out of it, so every single document gets split into n number of words.
And here's basically what my Solr response looks like:
<docID>
<title>My Doc Title</title>
<content>My Doc Title</content>
<date_published>My Doc Title</date_published>
</docID>
I believe there must be a way to integrate the words in here. I first thought of something like this:
<docID>
<title>My Doc Title</title>
<content>My Doc Title</content>
<date_published>My Doc Title</date_published>
<words>word</words>
<words1>word1</words1>
<words2>word2</words2>
<words3>word3</words3>
<wordsN>wordN</wordsN>
</docID>
But the faceting wouldn't be possible, as i have no idea how many words fields i would get per docID, then the faceting would have to be done across fields (which i;m not even sure it;s possible). I am trying to look into possible answers but I seem to be stuck... at the end, i need to make a faceting of n words that would get each single doc I have in my index. Thoughts would highly be appreciated.

我建议使用一个多值的单词字段并存储每个文档的单词列表。
拥有无限数量的 word\d+ 字段将使事情变得复杂。
如果您使用单个单词多值字段，您可以获得所有单词及其频率，这足以创建标签云。
I would suggest using a single words field that is multivalued and stores the list of words per document.
having unbound number of word\d+ fields will complicate things.
if you use a single words multivalued field you can get all the words along with their frequencies which should be enough for creating the tag cloud.
