有没有办法让 FlexSearch (https://github.com/nextapps-de/flexsearch) 只查找包含确切字符序列的结果？我尝试按照建议将分辨率设置为 25，将阈值设置为 22，也尝试使用深度，但我不断得到接近的单词（有时有点远，但至少长度匹配），但并不总是完全匹配我的序列。
我的索引词有时是 3 个字母的缩写，所以可能会扰乱上下文搜索。
如果您使用以下代码片段，通过输入 CTD，您会得到 CTD（好的）和 CDT（不好）。如果您输入 CAA，您会得到 CAA（好的）和 Candidate（不好）
var data =["CTD","CDT", "Candidate","CRT","CAA"];
(function(){
const index = new FlexSearch.Index({
charset: "latin:advanced",
tokenize: "full",
resolution : 25,
threshold : 22,
cache: true
});
for(var i = 0; i < data.length; i++){
index.add(i, data[i]);
}
var suggestions = document.getElementById("suggestions");
var userinput = document.getElementById("userinput");
userinput.addEventListener("input", show_results, true);
function show_results(){
var value = this.value;
var results = index.search(value);
var entry, childs = suggestions.childNodes;
var i = 0, len = results.length;
for(; i < len; i++){
entry = childs[i];
if(!entry){
entry = document.createElement("div");
suggestions.appendChild(entry);
}
entry.textContent = data[results[i]];
}
while(childs.length > len){
suggestions.removeChild(childs[i])
}
}
}());<!doctype html>

</html>我可能在那里遗漏了一些东西，但我相信有一种方法可以让库生成一个dumber索引和精确匹配，而不是这样一个具有紧密匹配的智能索引。
这符合您的要求吗？
附注
为了避免浪费时间搜索差异：我仅更改了
FlexSearch.Indexvar data = ["CTD", "CDT", "Candidate", "CRT", "CAA"];
(function() {
const index = new FlexSearch.Index({
charset: "latin",
tokenize: "full",
matcher: "simple",
cache: true
});
for (var i = 0; i < data.length; i++) {
index.add(i, data[i]);
}
var suggestions = document.getElementById("suggestions");
var userinput = document.getElementById("userinput");
userinput.addEventListener("input", show_results, true);
function show_results() {
var value = this.value;
var results = index.search(value);
var entry, childs = suggestions.childNodes;
var i = 0,
len = results.length;
for (; i < len; i++) {
entry = childs[i];
if (!entry) {
entry = document.createElement("div");
suggestions.appendChild(entry);
}
entry.textContent = data[results[i]];
}
while (childs.length > len) {
suggestions.removeChild(childs[i])
}
}
}());<!doctype html>

</html>只是为 Daniele Ricci 的答案添加更多想法：有时，如果请求包含数字，“简单”匹配器仍然会出现误报（如果我们正在寻找严格的模式）。同样，我的方法可能过于经验主义，无法获得完全正确的行为，但这里有一个产生误报的示例。将 tokenize 更改为 strict 可以改善这种情况，但随后您会丢失部分单词的匹配。默认匹配器似乎是误报较少的一个......仍然有一些......:(
如果你输入C3、C0或4，你会得到它们...
