阅读更多关于 Get page numbers of searchresult of a pdf in solr

问题 I'm building a web application where users can search for pdf documents and view them with pdf.js. I would like to display the search results with a short snippet of the paragraph where the search term where found and a link to open the document at the right page. So what I need is the page number and a short text snippet of every search result. I'm using SOLR 4.1 to index pdf documents. The indexing itself works fine but I don't know how to get the page number and paragraph of a search

Solr ExtractingRequestHandler giving empty content for pdf documents

The difference is when doing independently I am using BodyContentHander that comes with Tika instead of SolrContentHandler which is

How do I index rich-format documents contained as database BLOBs with Solr 4.0+?

阅读更多关于 How do I index rich-format documents contained as database BLOBs with Solr 4.0+?

问题 I've found a few related solutions to this problem. The related solutions will not work for me as I'll explain. (I'm using Solr 4.0 and indexing data stored in an Oracle 11g database.) Jonck van der Kogel's related solution (from 2009) is explained here. He describes creating a custom Transformer, sort of like the ClobTransformer that ships with Solr. This is going down the elegant path but is not using Tika which is now integrated with Solr. (He uses external PDFBox and FontBox.) This

问题 Is it possible to index rich document (pdf, office)... with data import handler using solr cell. I use solr 3.2. Thanks. 回答1: Solr Cell, aka ExtractingRequestHandler, uses Apache Tika behind the scenes, and the latter can easily be integrated into a DataImportHandler: <dataConfig>  <dataSource type="BinURLDataSource"/> <document> <!-- The value of format can be text|xml|html|none. this is the format in which the body is emited (the 'text' field)

Can anyone point me to a tutorial. My main experience with Solr is indexing CSV files. But I cannot find any simple instructions/tutorial to tell me what I need to do to index pdfs. I have seen this: http://wiki.apache.org/solr/ExtractingRequestHandler But it makes very little sense to me. Do I need to install Tika?
