Non exact search when clicking on a node : in the CNRS map on the V4, there is a node "trade". When clicking on this node, some the documents displayed in the side bar have only the term "trade-off" (ex. Insight into trade-off between wood decay and parasitism from the genome of a fungal forest pathogen). So either the matching is not set to "exact", or their is a pb with special caracters. Trade and trade-off should not be considered as same NGrams.

Some nodes do not have documents associated to them In the Glyphosate map, some node do not have documents associated to them. I don't know how this is possible since all nodes are associated to Ngram that have been extracted from some document ... Exemple here with "whc"
