[GSOC 2013] Question about indexing INEX dataset
Hi, I?m trying to use Omega to index INEX dataset for Letor. But omindex told me these xml files are unknown. Olly told me I could tell omindex to handle them as HTML. (Thanks Olly :) ) Is it appropriate? Parth, could you give me some suggestions? Thank you! Jiarong Wei
