There are inconsistencies between graph selection and displayed matching documents. For exemple, in Europa / Conference / Challenges 0.0.6.8.5.4, when selecting "personal data", the text below is match but contain neither "data" nor "personal" and "personal data" is not in a group. The text contains however the term "person" which mean that perhaps the search is looking at the stem of any token, which is not the required behavior. The search should look at exact match of any N-gram in the same group of the selected terms.

-- TITLE : Avoid the breakdown of shared reality Abstract In principle an immersive environment displays the same content to every individual participant. Of course they will perceive objects, situations and events from their unique embodied perspective, and even what they will consciously perceive will depend on their own particular dispositions – just as in physical reality. However, it need not be that way – the content displayed to each individual might be different without anyone knowing that this is the case. Two people interacting might be displayed as an assault to one person, but as a friendly conversation to another. Shared reality can break down without anyone knowing this, except through inevitable contradictions and conflicts that may arise. If the metaverse becomes the norm for conducting mass human interactions, ranging from work through medical care and leisure then shared social reality is an absolute requirement in order to avoid societal conflict and breakdown. Is it possible to regulate content to the extent that there is some minimal level of truth invariant across participants?
