searchEad
From Archives Portal Europe Wiki
Request url: https://api.archivesportaleurope.net/services/search/ead. This service is a POST-request.
This search-service delivers a list of archival descriptions with the requested search term. There is no distinction between the level of description. The user is able to filter results on various facets and order on various fields.
Request parameters
Three request parameters can be used to do a search in archival descriptions.
Empty Request example
{
"count": "5",
"startIndex": 0,
"query": "*",
"filters": [
{
"facetFieldName": "string",
"facetFieldIds": [
"string"
]
}
],
"dateFilters": [
{
"dateFieldName": "string",
"dateFieldId": "string"
}
],
"sortRequest": {
"sortType": "asc",
"fields": [
"string"
]
}
}
Basic Request example
{
"count": "5",
"startIndex": 0,
"query": "nepal",
"filters": [
{
"facetFieldName": "country",
"facetFieldIds": [
"7"
]
}
],
"dateFilters": [
{
"dateFieldName": "fromDate",
"dateFieldId": "1800-01-01_2"
}
],
"sortRequest": {
"sortType": "asc",
"fields": [
"date"
]
}
}
This example searches for archival descriptions with the term "nepal" and filters on the facet "country" with id = 7 (identifier for "NETHERLANDS") and date-facet "fromDate" with id = "1800-01-01_2" (identifier for the period 1800-1999), ordered ascending by date.
count
The resultlist is delivered in chunks of a certain size. Request parameter "count" describes the number of results that are in one chunk. Optional. Default value is 5.
startIndex
Request parameter "startIndex" enables you to select the results that you want to have. Counting starts at zero. If "count" = 5, the second chunk starts with startIndex 5, the following at startIndex 10, etc. Optional. Default value is 0.
query
Containing the search term(s). Required.
filters
Request parameter "filters" enables you to filter the result on facets. The facets are summarised in searchEad#facets.
dateFilters
Request parameters "dateFilters" enables you to filter the result on a certain period of time. The dateFacets are summarised in searchEad#date_facets
sortRequest
Request parameters "sortRequest" enables you to sort the result. The sortRequest contains two parameters: sortType and fields.
In "fields", you can provide a list of 1 or more fields. The resultlist is ordered on field[0] first, field[1] secondly, etc. The possible fields are:
- date: date of the archival material, provided in <unitdate>
- findingAidNo: number of the finding aid, provided by the repository in <eadid>
- title: description of the archival material, provided in <unittitle>
- referenceCode: identifier of the archival material, provided by the repository in <unitid>
In all situations you can sort ascending or descending by setting request parameter "sortType" "asc" or "desc" respectively.
Response parameters
The response contains a list of the descriptions where the requested search term(s) was/were found.
