The following page contains additional, more technical functionalities of the advanced help page.
When searching, the "indexed text" refers to everything crawled by the search engine. This always includes names, definitions, version and comments. Some items will also include additional text from associated items. For example, Data Elements include the text from its related Data Element Concept and Value Domain.
Selecting this option restricts Aristotle to only search for items with titles or names. This option is available for all searchable objects, including metadata types, pages, collections, documents, discussions and issues.
When logged in, selecting this option limits search results to only those items that are publicly visible to all users, including those without an account. This option is only shown to logged-in users as non-logged in users only have right to view to public content.
When searching select this box to limit results to only those items that are within a workgroup a user belongs. This option is only shown to logged-in users.
When searching Aristotle-MDR performs spellchecks against search terms, and if there is a low number of results will recommend an alternate search term. Along with this, if a search returns zero results, Aristotle-MDR will remove any filters such as item type or date restrictions to automatically broaden the search corpus. Any time the search is changed, such as spelling correction or filter removal, a notification will appear under the search bar to let users know.
When searching without selecting an item type or category, the search engine searches across everything in the registry.
When searching there are a few advanced options available to make searching easier. These can be entered into any search box using the keyword:search_term format.
Certain tokens and field names, such as name, or version, can be used to limit results when searching. These will force the search engine to only return results where terms appear in those fields.
Sample queries are shown below:
status:argument
Filters items to those that have the given registered state. This can only be used for items which can be registered. Possible values:
incomplete (or inc),
candidate (or can),
recorded (or rec),
qualified (or qual),
standard (or st),
preferred (or pref)
(short for Preferred Standard),
superseded (or sup), or
retired (or retired)
Sample: Business version:1.0.0
Result: Returns items where Person appears anywhere in the indexed text, and also has a version of "1.0.0".
id:argument or identifier:argument
Filters items that have an additional namespaced identifiers.
Examples:
id:123485 - Returns all items that have an extra Identifier of "123485", with any version number.
id:my_org/123485 - Returns all items that have an extra Identifier of "123485" in the namespace "my_org", with any version number.
id:my_org/123485/2.0.1 - Returns the item that has the extra Identifier of "123485" in the namespace "my_org", with the version number "2.0.1".
name:argument
Filters items where the given argument is in the name field of the object.
name:Person
Result: Returns items with "Person" in the name
namespace:argument
Filters items that have an additional namespaced identifiers with the specified namespace.
Sample: Person namespace:my_org
Result: Returns items where Person appears anywhere in the indexed text, and also has a namespace of "my_org".
type:argument
Filters items to be of the given item type. This can be any metadata type, help page, or other indexed content.
For examples, see below.
version:argument
Filters items where the given argument is in the version field of the object. Note: Because of the nature of the search engine, version queries need to be at least 3 characters long.
Sample: Person version:1.0.0
Result: Returns items where Person appears anywhere in the indexed text, and also has a version of "1.0.0".
uuid:argument
Filters items where the given argument is in the UUID field of the object.
Sample:
uuid:beb4a870-8c40-11eb-ac36-0242ac150007
Result:
Returns items that have an identifier of "UUID - beb4a870-8c40-11eb-ac36-0242ac150007".
tc:argument
Filters datasets and distributions which have temporal coverage within the bounded limits. Dates must be in iso format YYYY-MM-DD...YYYY-MM-DD. Dates can be uncomplete.
Sample:
tc:2020-06-11...2021
Result:
Returns items which have temporal coverage with the dates from 2020-06-11 to 2021-01-01.
bb:argument
Filters datasets and distributions which have spatial coverage within the bounding box. Bounding box must be in the format ('minimum_longitude','minimum_latitude', 'maximum_longitude', 'maximum_latitude')
Sample:
bb:-180,-90,180,90
Result:
Returns all items which have a bounding box within these bounds. This query will return every dataset and distribution which has a spatial coverage because these are the latitudinal and longitudinal limits.
When searching, you can enter a type along with the name of the object type to further restrict your search. The type must not include spaces, which should be removed, or replaced with underscores or hyphens. For an even shorter query, type names can be abbreviated to the first letter of each word in the type name.
This is the same as selecting options in the Item Type dropdown on the search page.
Sample queries are shown below:
Age type:property
Returns only properties with "Age" in the text
Person type:objectclass
Returns only Object Classes with "Person" in the text
Person type:object_class
Returns only Object Classes with "Person" in the text
Person type:oc
Abbreviated way to return only Object Classes with "Person" in the text
Person Age type:dec
Abbreviated way to return only Data Element Concepts with "Person" and "Age" in the text
Person Age type:dec type:de
Abbreviated way to return Data Element Concepts or Data Elements with "Person" and "Age" in the text
Keyword queries can be used together to create complex queries.For example, this query - Person Age name:Person type:dec version:1.2.3 - searches for items that meet the following criteria:
Person Age - "Person" or "Age" in the indexed text
name:Person - "Person" appearing in the name
type:dec - Are of the type Data Element Concept
version:1.2.3 - Have a version of "1.2.3"
