Hi ,

I am trying to join the results of two different queries from Pubmed and make a tag cloud by assigning frequencys to all terms that arise using POS tagger.

I used document grabber to query in pubmed, now when I use the node concatenate , many files are represented as question marks , although the document grabber has retrieved proper results. Why is it so ?

Is there any other node which i could use to combine the results of both queries into one table ?





Is it the joiner node you are after?



I've the same problem and yes, one of the 2 tables comes from a joiner node. How can I manage this issue?



EDIT: problem fixed
