Query modules

In the “Query conditions” section, some values might be linked to other modules. E.g. within the “Identification” group the fields “Taxa” and “Terms” are linked to the “DiversityTaxonNames” and “DiversityScientificTerms” modules. You can also add “linked” values to your query condition.

1. Select the operator that determines how the entries are integrated into the search. See an explanation of all available operators in the table below.
