我想知道这是否是展示和讨论我的用例的正确位置。如果没有，请帮我将这个问题重定向到其他地方。
我在社交媒体网站上使用ES 5.2作为我们的搜索功能（看起来像youtube）。而且我很难找到如何搜索带有剧集编号的视频。 例如：
$ag-icons-path: '~ag-grid/src/styles/icons/';
$ag-mat-icons-path: '~ag-grid/src/styles/material-icons/';
// Change the primary / accent colors
$primary-color: red;
$accent-color: green;
@import '~ag-grid/src/styles/ag-grid.scss';
@import '~ag-grid/src/styles/ag-theme-material.scss';
虽然我用剧集编号更改了关键字搜索，但我总是得到相同的结果。
{"id": "1","title": "Four Beautyful Sun Flower - Episode 01"}
{"id": "2","title": "Four Beautyful Sun Flower - Episode 15"}
{"id": "3","title": "Four Beautyful Sun Flower - Episode 17"}
{"id": "4","title": "Four Beautyful Sun Flower - Episode 23"}
{"id": "5","title": "Sun Flower In Morning - Episode 01"}
{"id": "6","title": "Sun Flower In Morning - Episode 15"}
{"id": "7","title": "Sun Flower In Morning - Episode 17"}
{"id": "8","title": "Sun Flower In Morning - Episode 23"}
这是我得到的结果
{ "query": {
"match": {
"title": "Four Beautyful Sun Flower Episode 17"
} } }
我希望这一集会出现在第一集中。但结果始终是相同的顺序。除此之外，我只想获得四个美丽的太阳花电影，但结果显示机器人四美丽的太阳花和早晨的太阳花。 有人可以帮我怎么做这样的搜索。我尝试了ES页面文档中的所有建议，但仍无法正常工作。
这是重现此案例的bash脚本。

非常感谢您的时间。
答案 0 :(得分：0)
您正在使用带有"min_gram": 3的edge-ngram过滤器。这意味着将忽略任何小于3的令牌。如果您浏览分析链，则首先使用"Four Beautyful Sun Flower Episode 17"标记生成器将查询standard拆分为标记。这会产生
Four
Beautyful
Sun
Flower
Episode
17
接下来应用小写过滤器，产生以下标记：
four
beautyful
sun
flower
episode
17
接下来是autocomplete_filter，它运行在上述每个标记上。由于17小于3个字符，因此将其忽略。
如果您将min_gram更改为2 "min_gram": 2，您将获得正确的结果！
