Word2vec 个性化搜索实现 +Scrapy2.3.0(爬取数据) + ElasticSearch7.9.1(存储数据并提供对外Restful API) + Django3.1.1 搜索
本仓库为搜索端网站端代码，爬虫端请前往https://github.com/mtianyan/FunpySpiderSearchEngine 获取
- 知乎答案问题爬虫存入ElasticSearch
- 全文搜索(需结合网站端一起使用)，搜索词高亮标红
- Redis实现的实时三站已爬取数目展示，热门搜索Top-5
- word2vec改变ElasticSearch(function_score, script_score)评分， 比如历史上你搜索过Apple， 会使得Apple经过 Word2vec 计算出的苹果，乔布斯等关键词打分排名靠前
word2vec 模型训练全过程请查看FunpySpiderSearchEngine项目Word2VecModel 中README word2vec 使用，影响ElasticSearch打分，请查看mtianyanSearch中相关代码
核心打分代码:
"source": "double final_score=_score;int count=0;int total = params.title_keyword.size();while(count < total) { String upper_score_title = params.title_keyword[count]; if(doc['title_keyword'].value.contains(upper_score_title)){final_score = final_score+_score;}count++;}return final_score;"
标题每包含一个相关词，分数加倍
