[Json Demo](https://joway.wang/search.json)
[中文: Hexo折腾记——静态站点搜索](https://joway.wang/posts/Hexo/2016-04-23-hexo-search.html)
## Dependence
Tokenize Dependence: [Segment](https://github.com/leizongmin/node-segment)
Supports chinese and english tokenize .
## Installation
$ npm install hexo-tokenize-search --save
## Usage :
### Config the search json
You can custom the json path in your global _config.xml
search:
path: search.json
When the plugin is installed , it will auto generator search.json (by default) in your root context.
The json is a array and each element will be included 5 field like this :
``` json
[
{
"title": "xxxxxx",
"url": "xxxxxx" ,
"content": "xxxxxx" ,
"title_tokenize": "xx xx xx xx",
"content_tokenize": "xx xx xx xx"
},
{
...
}
]
```
I removed html tags in the content field and remove punctuations in the tokenize field .
### Use the search.json
You can use your query to custom sort the json array.
There is my simple example:
> search.html
``` html
```
> search.js
function getParameterByName(name, url) {
if (!url) url = window.location.href;
name = name.replace(/[\[\]]/g, "\\$&");
var regex = new RegExp("[?&]" + name + "(=([^]*)|&|#|$)"),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, " "));
}
function calcScore(key, tokenize) {
var score = 0;
for (var x = 0; x < tokenize.length; ++x) {
if (tokenize[x] == null) {
break;
}
for (var i = 0; i < key.length; ++i) {
for (var t = 0; t < tokenize[x].length; ++t) {
if (tokenize[x][t] == key[i]) {
score++;
}
}
}
}
return score;
}
function addCountToJson(key, json) {
for (var i = 0; i < json.length; ++i) {
// 题目匹配权重100 , 内容匹配权重1 , 匹配算法: 单字匹配 (待优化)
json[i]['score'] = calcScore(key, json[i].content_tokenize) + calcScore(key, json[i].title_tokenize) * 100;
}
}
// 按 json 元素 score 值进行排序
function quickSort(json) {
if (json.length <= 1) {
return json;
}
var pivotIndex = Math.floor(json.length / 2);
var pivot = json.splice(pivotIndex, 1)[0]; // 基准
var left = [];
var right = [];
for (var i = 0; i < json.length; i++) {
if (json[i].score < pivot.score) {
left.push(json[i]);
} else {
right.push(json[i]);
}
}
return quickSort(left).concat(pivot, quickSort(right));
}
window.onload = function () {
var query = getParameterByName('query');
if (query == null) {
query = '';
}
$(".st-default-search-input").val(query);
$.get("../search.json", function (result) {
addCountToJson(query, result);
result = quickSort(result);
for (var i = result.length - 1; i >= 0; --i) {
$("#result").append('' + result[i].title + ' 评分: ' + result[i].score + ' ');
}
});
};
