Subject Re: How to use DataImportHandler with ExtractingRequestHandler?
Date Thu, 03 Sep 2009 17:49:43 GMT
Hi Khai,

a few weeks ago, I was facing the same problem.

In my case, this workaround helped (assuming, you're using Solr 1.3): 
For each row, extract the content from the corresponding pdf file using 
a parser library of your choice (I suggest Apache PDFBox or Apache Tika 
in case you need to process other file types as well), put it between




and store it in a text file. To keep the relationship between a file and 
its corresponding database row, use the primary key as the file name.

Within data-config.xml use the XPathEntityProcessor as follows (replace 
dbRow and primaryKey respectively):

<entity name="pdfcontent"
   <field column="pdftext" xpath="/foo"/>

And, by the way, in Solr 1.4 you do not have to put your content between 
xml tags: use the PlainTextEntityProcessor instead of XPathEntityProcessor.
