弹性搜索单词建议
Elastic Search word suggestion
我们希望弹性搜索建议在索引中找到的词。我们正在使用版本：5.6.4.
如果我键入 "head"，它应该建议 "headquarters"，这是在索引中找到的一个词。最好它应该按出现次数对建议进行排序。
我试过几个教程，但它们都是 return 整个内容项而不是单词本身。我使用文档得出的最接近结果如下：
GET test_content/_search?pretty
{
"suggest": {
"text": "head",
"my-suggestion": {
"term": {
"field":"autocomplete"
}
}
}
}
但它没有给出任何结果，直到我输入："headquarte"。
当我键入 "lead" 时，我期望 "leadership"，但得到的结果是："land"。错别字纠正可能很好，但不是我目前想要的。我首先想要获得一个稳定的工作单词建议功能，稍后可能包括拼写错误更正。
我也试过 edgeNGram 过滤器，但没有得到任何正确的结果。 whitespace 过滤器现在应该没问题。前缀搜索对我来说没问题。
