多领域联合过滤技术:高效实现实战解析
以下是一个高效的JavaScript多领域联合过滤器代码示例,用于实现标题、关键词、描述和正文的高效过滤:
javascript
// 生成标题
const titleFilter = new TextFilter({
title: '标题',
filter: (query) => {
return !query.match(/^(.?)(\s)(.?)(\s)(.*?)$')
}
});
// 生成关键词
const keywordFilter = new TextFilter({
keyword: '关键词',
filter: (query) => {
return !query.match(/^(.?)(\s)(.?)(\s)(.?)(\s)(.*?)$')
}
});
// 生成描述
const descriptionFilter = new TextFilter({
description: '描述',
filter: (query) => {
return !query.match(/^(.?)(\s)(.?)(\s)(.?)(\s)(.?)(\s)(.*?)$')
}
});
// 生成正文
function generatePostText(postContent) {
const postTitle = postContent.match(/^(.?)(\s)(.?)(\s)(.?)(\s)(.?)(\s)(.?)$')
? postTitle
: '';
const postKeywords = postContent.match(/^(.?)(\s)(.?)(\s)(.?)(\s)(.?)(\s)(.?)(\s*)$')
? postKeywords
: '';
const postDescription = postContent.match(/^(.?)(\s)(.?)(\s)(.?)(\s)(.?)(\s)(.*?)$')
? postDescription
: '';
return {
title: postTitle,
keywords: [...postKeywords.split('\n').filter(word => word !== '')],
description: postDescription,
content: postContent
};
}
// 示例应用
let search = new SearchEngine({
titleFilter,
keywordFilter,
descriptionFilter,
generatePostText,
});
// 示例搜索语句
search.search('关键词:技术', '标题:技术', '描述:技术');
console.log(search.searchResult);
