基于Lucene的PDF文档的全文检索的实现

在Lucene的全文检索中,直接对PDF文档进行全文检索几乎是不可能的。在实际应用中又需要对大量的PDF文档进行检索,通过Xpdf工具先对PDF文档转换为TXT文本,然后对TXT文本建立索引,在进行检索时通过文件名实现和原始PDF文档的一一对应,最终实现PDF文档的全文检索功能,同时还能实现对PDF文档所检索的包含关键词的内容进行高亮显示,实现全文检索的功能,通过实际项目应用,检索效果能够达到很好的效果。

Implementation of PDF Full-text Based on Lucene

In the Lucene full-text search in PDF documents directly to the full-text search is almost impossible.In practice,they need to retrieve a large number of PDF documents,this article first,through the Xpdf tools convert PDF documents to TXT text,and then the TXT text indexing,search through the file name during the implementation and the original PDF document one by one corresponds to,and ultimately the full-text search of PDF documents,but also enables PDF documents to re- trieve content that contains keyword highlighted,to achieve full-text search function.
