将出色的搜索引擎链接到搜索框，该引擎提供“可能已经有答案的问题”

#1 楼

的确，问一个问题确实带来了更多相关条目。但是，如果您要查找特定的问题，则不一定有帮助。有时候，您需要完全匹配，而有时又需要与您要的内容相似。

删除搜索引擎以查找完全匹配的危险不仅在于最终会出现一些问题经常被提出来，但其他人则被完全忽略。一个很好的例子是在Amazon vs. eBay上搜索产品。当您在eBay上寻找商品时，总是会找到完全匹配的商品，并且可以形成有意义的“后续搜索”，例如violin "strings" stock -book -super -elements

在Amazon上查询相同的搜索词组会显示以下列表项目项：

Thomastik Peter Infeld 4/4 Violin Strings Set with Platinum E
Dr Thomastik-Infeld 130 Dominant Violin String, Single E String, 130, 4/4 Size, Aluminum Wound, Ball End
Thomastik-Infeld 135BMS Dominant Violin Strings, Complete Set, 135Bms, 4/4 Size, Chrome Steel Loop End E String
Thomastik-Infeld VI100 Vision Violin Strings, Complete Set, 4/4 Size
D'Addario NYXL1046 Nickel Plated Electric Guitar Strings, Light
Jascha Heifetz plays Great Violin Concertos
3dRose Greeting Cards, Bass and Cello, 6 x 6 Inches, String Instruments Violin (gc_200920_1)
Thomastik-Infeld VI100.34 Vision Violin Strings, Complete Set, 3/4 Size
Roth Waller No.5 Wooden Violin Chin Rest New/Old Stock
Thomastik-Infeld VIT100 Vision Titanium Solo Violin Strings, Complete Set, 4/4 Size, Synthetic Core

因此前10个项都不符合所述搜索词组。并按相关性排序；按其他任何方式排序会在顶部附近产生更差的匹配，例如Interieur Aux Instruments De Musique - Graphique de France Raoul Dufy Birthday Card

虽然搜索购买时这更成问题，但在YouTube上实现了类似亚马逊的近似搜索算法。键入查询Jack Rissa giggle时，出现以下视频（括号中的描述）：

一些统计信息：


这些视频中的任何一个都没有超过标题和说明中的三个关键字之一。
第二个视频已经没有搜索词组中的任何关键字，只是部分匹配。
第七个视频（还有许多后续的搜索词）甚至都没有与我的搜索词相关的词，而是主要（如果不是全部）基于我的视频历史记录。

实际上，有一部视频的标题仅包含4个词，其中包括这三个。即使包含确切的标题和/或描述（带引号或不带引号），也找不到该视频：仅是其视频URL。观看该视频似乎会将其撞到结果列表一段时间，然后又消失了。

随着越来越多的网站搜索转到“这就是您的历史，这是我们的建议”-我绝对尊重StackExchange留下的标准搜索引擎可以用来查找确切的短语。话虽如此，我也同意@WendiKidd和其他人的观点：我自己经常使用“问-问”按钮来找到我要寻找的答案。但是话又说回来，尤其是在Math.SE上，我真的很欣赏能够键入我需要解析的复杂数学公式，甚至在Google机器人接触之前就可以在Math.SE上找到它的能力。对我来说，这是一个更大的问题，是搜索框用于查找确切短语或查找近似值的默认行为。
