This tool uses all the data and enrichments available via the Media Suite. See Data page for more information.
At this moment (version 4) the search API detects when a user does a boolean/wildcard query by looking for the keywords:
OR
AND
NOT
*
?
” “
Exact expression
Nesting and search order
Nesting queries is supported
Capitalization
Query corrections/suggestions
Note: Future work includes supporting proximity parameters.
To facilitate more precise queries, users can use “search layers”, which are aggregations of metadata fields. At this moment (version 4) we support three layers for all collections:
Tip : To see which fields have been aggregated in each cluster, hover over the field cluster.
Users can determine in which field or group of fields they want to search for their query expression. For example, a user may want to search for a specific character’s name (e.g., Mies Bouwman). In that case:
Tip : To see the list of metadata fields per collection, as well as their definitions, use the Collection Inspector tool.
You can limit your query to a specific period of time. It is important to keep in mind that collections often include several fields of the type “Date”. To see the metadata fields that are of the type “Date”, you can use the “Inspect” tool and consult the metadata dictionaries.
The timeline visualisation shows a histogram or a line chart with the amount of documents (relative or absolute) which match your query.
To generate a timeline visualization of your results based on time, first select a date field (see item before.
Mouse-overs show the year and the number of results per year.
Please note that the statistical unit (what is being counted) are documents (programs, articles, interviews), and not the number of occurrences of the term within a document; that is: “1” means one document (i.e., one television programme, one newspaper article, one oral history interview).
The relative frequencies (percentages) are calculated by dividing the number of documents with hits by the total number of documents within one year (or week, day, depending of the ‘bucket’).
This normalization helps to compare result numbers of different collections.
Please also note that each record possibly can have multiple occurrences of the selected date field (this happens clearly in the audio-visual collections of The Netherlands Institute for Sound and Vision, e.g., a rebroadcast), making it possible that there are more dates found that the number of search results. The number of cases can be seen in the “Outside range” summary in the chart panel:
Faceted search: Facets include aggregations of terms from the metadata fields of the type “Keyword field”, the terms included in each facet can be used for filtering the results of your query. To see the metadata fields that are of the type “Keyword”, you can use the “Inspect” tool. At this moment (version 3) we support:
List of search results: The Search tool gives a list of search results after entering your query and filters. You can in this list:
Order results per relevance (description to be included soon)
Order results per date: it chooses the date field you used for filtering
