EASY can be searched via a general free-text search. It searches in the metadata of all published datasets, but it does not extend into the contents of the uploaded files in datasets. Please use English as well as Dutch words for optimal search results.
A result list shows datasets that match the chosen criteria, mentioned in the 'Criteria' at the top of the list. Criteria may be removed individually using the 'x' mark beside them. Sort options are also available; clicking toggles the sort order (ascending/descending). On most result lists, refine options are available (at the right-hand side). Use those options to filter within the list (e.g. search within the result list). For more about refining and the meaning of the values of the field 'Access', refer to the help on refine (use the '?' mark next to 'Refine').
To search specific fields (and/or any field), use the 'Advanced search' link. To get a list of all published datasets, start with the 'Browse' link.
Please enter one or more terms in the search box. All terms occur in the document. For example: archaeological predictive modelling.
Use English and Dutch terms For example: Enter human rights, but also mensenrechten. Hence: enter human rights or mensenrechten.
Quotation marks can be used to find word combinations. For example: enter “health care”. and you will find records where the words ‘health’ and ‘care' are adjacent.
You can search on terms that are specified only partially by using an asterisk: * For example: econom* also provides records about economical, economics, economic, economy et cetera
You can use question marks: ? as a subsitute for any letter. For example: sh?p provides all records featuring 'ship' or 'shop'; ship???? provides all records where 'ship' is followed by four letters (i.e. 'shipping', 'shipment'); ship????? provides all records where ship is followed by five letters (i.e. 'shipwreck', 'shipments').
Boolean searching in search box
Search terms can be combined using ‘AND’,‘OR’ and ‘NOT’.
‘AND’: both terms should occur, but the order is not important.
‘OR’: one of either the terms or both terms should occur (e.g. with synonyms or words in different languages), the order is not important.
‘NOT’: the first term should occur and the second not.
youth AND child: Records contain both 'youth' and 'child'.
youth OR child: Records contain either 'youth' or 'child' or both.
(youth OR child) AND language: Records contain either 'youth' or 'child' or both, and also 'language'.
youth NOT language: Records contain 'youth' and not 'language'
+youth -criminal: Records contain 'youth' and do not contain 'criminal'
Refine options are available in a list of results. Use these options to filter within the list. After refining, a narrowed-down list of results appears (which may be refined again, depending on the criteria chosen). For other result lists options, e.g. removing criteria, refer to the search help (use the '?' mark next to 'Search').
Searching within results
Search and Advanced search are available on any list of results. That may be a list of published datasets obtained through search or browse or a list of your deposited datasets obtained through the 'My datasets' link. The functioning of search is explained in the search help (use the '?' mark next to 'Search').
Browsing within results
Additional attributes of the dataset metadata may be shown with values which can be selected. For example, selecting 'Social sciences' from a list of audiences produces the result list again but this time with only datasets that have 'Social sciences' as Audience in their metadata. Note that only values that are present in the datasets in the result list are shown. If no dataset in the list has an Audience in Social sciences, then the value 'Social sciences' is not shown.
Note that Audience has a tree structure, so after selecting 'Social sciences' you get a new list of possible values within Social sciences. Selecting 'Social sciences' actually selects datasets that have Audience set to either 'Social sciences' or a more specific audience within Social sciences.
The access policy of datasets (within the result list) may show one or more of the following values:
Open, i.e. unrestricted access for all registered EASY users
Restricted -request permission, i.e. access for registered EASY users, but only after depositor permission is granted
Restricted -'archaeology' group, i.e. access restricted to registered group members, in this case 'archaeology' group members
Other, i.e. the data is not available via EASY (they are either accessible in another way or elsewhere)
Note that the access policy of the dataset may be an approximation of the actual access settings of its files. For example, the dataset may be 'Restricted -request permission', implying that its data requires permission. But some documentation files may be accessible without requiring permission.
On archaeological datasets (i.e. datasets with Audience: Humanities > Archaeology), additional attributes may be available that are specific to this discipline.
