Advanced text search



The advanced search allows you to search in specific fields of the Rhea database. This is useful when you search with an ambiguous term, for instance a numeric record identifier that may exist in several fields. You can also combine several query terms with Boolean operators (AND, OR, NOT).

Once you are familiar with the field names, you can directly enter your field-specific queries into the website's text search box. For occasional usage you may find the advanced search query builder that is shown in the next section helpful.

Advanced search query builder

You can access the advanced search query builder from the home page or from any page by clicking the link Advanced search next to the text search box.

By clicking the red All button, you get a drop-down menu with the list of the search fields. By default the Boolean operator that combines several fields is set to AND, click on it to change this selection.
