Screenshot of the AlvisIR Food search engine results to the query {taxon}*∼livesin fruit which means “which microorganisms live in fruit?”. Curly brackets are used to specify a query about the three main categories of entities, followed by the star * to indicate that they are all to be displayed (and mandatory): i.e. a query with all microorganisms is written as {taxon}*, a query with all habitats as {habitat}* and a query with all phenotypes as {phenotype}*. The presence of the tilde character ∼ (which is not mandatory) indicates that a query concerns a relation between entities (here, the Lives_in relation).
