Ettore, Lucas, thanks a lof for your answers, that's what I was looking for. Searching for an entity based on a label + language (and optionally additionnal criteria like instance of) looks like a reasonable use-case, this could be "packaged" inside magic triples to make this feature directly available in SPARQL (as other triplestores with full-text/index-based search are doing).
