Why the parallel concordance feature is not available in the corpus?

The parallel concordance feature is available for specific corpora only. These are called parallel corpora, meaning corpora that consist of the same text translated into two or more languages. The texts have to be aligned (matching segments, usual sentences, are linked). You can check which corpora are parallel if you go to select corpus -> advanced tab -> parallel (in the right menu). 

For more information, please see our guide on parallel concordance.
