Performing a search

The Research Vocabularies Australia portal search allows you to search across vocabulary metadata records as well as the resources (SKOS concepts, schemes, collections, etc.) contained within versions of each vocabulary.

To perform a search, type your search query into the search bar displayed at the top of the each Research Vocabularies Australia page, and click the Search button. The search will be executed, and you will be navigated to the search results page, where you can further refine your search.

Search Results page

The Research Vocabularies Australia Search Results page combines two separate searches: one for vocabulary metadata records, and the other for resources (SKOS concepts, schemes, collections, etc.). The separate searches are accessed using a set of tabs displayed at the top and bottom of the search results. By default, the Vocabularies tab is selected for all new searches.

Info

The query term(s) you enter in the search bar apply to both search results tabs. The settings for results sorting and the number of results per page are also applied to both search results tabs. However, the filters shown at the left-hand side, are type-specific, and only apply to the search results tab ("Vocabularies" or "Concepts, etc,") to which they are added.

You can switch back and forth between the tabs without losing your search filters and results.

Filtering

Image Added

Filters provided down the left-hand side of the search results page assist you in narrowing down your search results by specific vocabulary/resource metadata values or attributes (e.g., subject or access method). The count of vocabularies matching each filter is displayed in parentheses to the right of the filter label.filter categories displayed are dependent on which search tab is selected. 

To add a filter to your search, click the checkbox or filter label. Upon selecting the filter, the search will be updated to show only results which contain the selected filter. Repeat the process to add additional filters. 

Note that the display of the large filter categories (e.g. Subject and Publisher) are often truncated in order to optimise the search page display. Where a filter category list has been truncated, a View More… link is shown after the last displayed value. Click the link to show the complete list of values. Once expanded, a View Less… link is shown after the last displayed value. Click the link to truncate the list again.

Info

Filters are applied to your search as a conjunction ("and") of disjunctions ("or"). This means that in order to match your search, a vocabulary/resource must have at least one or more of the values within each filter category applied to a search.

Filter counts

There are two types of counts which can be displayed for a filter.

The count of the current search results, which is displayed in parentheses to the right of each filter label, is the count of vocabularies/resources matching the filter in your current search results.

The other type of count is the filter addition count. This count is displayed within a filter category, after at least one filter in the category has been selected. The addition count indicates the number of vocabularies/resources which contain the filter value which are not present in your current search results. Applying the filter will add the additional results to your search. The filter addition count is not displayed for selected filters or for filters where there are no additional results to add.

Note

Filter counts do not take collapsing of search results into account. Please refer to the Collapsing of search results section below for more information.

Scrollable filter categories

In order to maximise screen real estate, large filter categories such as Subject and Publisher, are displayed as lists in a scrollable container.

A filter has been incorporated into the container to assist in narrowing down the list of values. Start typing in the text area to begin filtering the list. Click the orange X button to clear the filter. Note that each time your search is updated, the text area (and therefore the filtering of the list of values) will be reset.

Resetting a search

To clear a search, click the Reset search button displayed in the Current search section on at the top left-hand side of the search results page. Resetting the search clears all search terms and filters for both tabs, and sets all search results display preferences (e.g., sorting) back to default values. Note that the button is disabled when there is nothing to reset.

...

Whenever a query term is active, the default sort order for search results is Relevance, where each record result in a set of search result results is given a ranking based on how closely a record result matches the entered search parameters. The records results are then sorted by ranking highest to lowest. The default sort order can be changed using the Sort by: dropdown displayed in the search results header and footer. When no query terms have been entered, the default sort order is changed to 'Title A-Z', as no ranking can be applied.

...

By default, 15 records are displayed per search result page. If there are more than 15 records, they are displayed on subsequent pages. The number of records displayed per page can be changed using the Show: dropdown displayed in the search results header and footer. The pagination links displayed in the search results header and footer can then be used to navigate between pages.

Search result components

Vocabulary search results


The vocabulary title, publisher(s) and in-context search term highlighting is are displayed for each search result.

...

The vocabulary title displayed in each search results result is a hyperlink to the record view page for the vocabulary. Click the link to access the full record view for the vocabulary.

The widgetable label is displayed against any vocabulary which can be used the RVA Vocabulary Widget. Hover your mouse over the label to find out more.

Concepts and other resources search results

Image Added

The resource display title, IRI, in-context search term highlighting and vocabulary details are displayed for each search result.

The in-context highlighting provides you with an easy way of understanding why a resource has been returned by a search. The metadata field where the match was made is displayed in parentheses at the end of the context snippet, e.g., “(in SKOS prefLabel)”. At most two context snippets are provided for each type of field, per search result. Where no search terms have been entered for a search, the in-context search term highlighting is replaced with the first few lines of the resource definition/description (SKOS definition/DC Terms description).

The resource display title displayed in each search result is a hyperlink to the record view page for the vocabulary. Click the link to access the full record view for the vocabulary.

Where a resource has been published to the Linked Data API (SISSVoc), a link to access the resource in the Linked Data API will be displayed at the bottom of the search result.

A more detailed view of the resource can be accessed by clicking on the  View resource details button displayed at the bottom of each result.

Where collapsing (see Collapsing of search results) has occurred, the collapsed versions/vocabularies can be accessed by clicking on the View other versions/View other vocabularies button shown at the bottom of the search result.

Understanding search results

...

  • Searches for a single query term generate results containing any vocabularies which contain the entire word or the "stem" of the word in an indexed field. Refer to the Stemming section above.
  • Searches for multiple terms (i.e., space-separated) are treated as disjunctive queries: at least one term must match for a vocabulary to be included in the results.
  • The default sorting for searches with at least one query term is by ‘Relevance’, where each vocabulary in a search result is given a ranking based on how closely the vocabulary matches the entered parameters. 
  • The default sorting for searches with no query terms is by ‘Title A-Z’.
  • The following vocabulary metadata fields are analysed against your search terms:

    • Vocabulary title
    • Description
    • Notes
    • Concepts contained in the current version of the vocabulary (if available)
    • Top concepts
    • Subjects
    • Related entity titles/names (e.g., publisher)

Collapsing of search results

The collapsing of search results combines multiple results into a single result for display based on a set of shared properties. Collapsing has been implemented as a way of preventing the same resource  being repeated over and over in the search results, where the resource is contained in multiple versions of one or more vocabularies.

By default, resources with the same IRI from the same vocabulary will be collapsed into a single search result. The collapsing settings can be changed by clicking on the Advanced options button displayed at the bottom of the search results.

OptionDescription

Collapse results with the same IRI, per vocabulary

Resources with the same IRI from any version of the same vocabulary will be collapsed into a single search result.

The primary result for a resource is from the vocabulary's version that has status "current", if there is one, otherwise, it is from the version that has the most recent release date.

Where collapsing has occurred across versions of a vocabulary, the other versions can be accessed by clicking on the View other versions button shown at the bottom of the search result.

Collapse results with the same IRI

Resources with the same IRI from any vocabulary or version will be collapsed into a single search result.

The primary result for a resource is from a vocabulary's version that has status "current", if there is one, otherwise, it is from the version that has the most recent release date.

Where collapsing has occurred across vocabularies, collapsed vocabularies can be accessed by clicking on the View other vocabularies button shown at the bottom of the search result.

 

Don’t collapse results

No collapsing of results is applied. All instances of a resource are displayed as individual search results.

Note

Collapsing and the effect on filters

When collapsing is enabled, the available filters and associated current search results count (see Filter counts) do not take into account the collapsed versions/vocabularies. The filters available only reflect the properties of the resources used as the primary results (the result others are grouped into).

Image Added

The filter addition counts represent the number of individual vocabularies/resources in the search index which contain a filter value and are not present in your current search results. These counts do not take into account the effect collapsing may have on the final count of results. Refer to the image below for an example.
