Request parameters
Three request parameters can be used to do a search in archival descriptions.
eg.
{
"count": 5,
"startIndex": 0,
"query": "nepal",
"filters": [
{
"facetFieldName": "country",
"facetFieldIds": [
"7"
]
}
],
"dateFilters": [
{
"dateFieldName": "fromDate",
"dateFieldId": "1800-01-01_2"
}
]
}
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).
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 searchterm(s). Required.
filters
Request parameter "filters" enables you to filter the result on facets. The facets are summarized in searchEad#facets.
dateFilters
Request parameters "dateFilters" enables you to filter the result on a certain period of time. The dateFacets are summarized in SearchEad#date_facets
Response parameters
The response contains a list of the descriptions where the requested search-term(s) was/were found.
eg.

"startIndex": 0,

}
totalResults
The response parameter "totalResults" gives the number of results.
startIndex
The response parameter "startIndex" gives the number of the chunk you requested.
totalPages
The response parameter "totalPages" gives the number of chunks.
eadSearchResults
Enumeration of the results. A result could be a holdings guide, a source guide, a finding aid, or a descriptive unit (ie. a sublevel component). They are all optional except "id".
| id | Internal APE identifier of the result |
| unitId | Identifier of the result provided by the repository |
| unitTitle | Description of the result |
| unitTitleWithHighlighting | Description of the result, with the mark "<em>" to emphasize the search term that was used in the search request. |
| unitDate | Date of creation of the result. |
| scopeContent | More descriptive information about the result. |
| scopeContentWithHighlighting | More descriptive information about the result, with the mark "<em>" to emphasize the search term that was used in the search request. |
| hasDigitalObject | TRUE/FALSE |
| langMaterial | Language in which the result is created. |
| language | Language of the description of the result. |
| docType | Type of archives describing document where the result is found : "Finding Aid", "Holdings Guide", "Source Guide" or "Descriptive Unit". |
| level | Type of result: "archdesc" for highest level description or "clevel" for subordinate components |
| fondsUnitId | Identifier of the fonds provided by the repository. |
| fondsUnitTitle | Title of the finding aid. |
| repository | Name of the repository holding the fonds |
| repositoryCode | Code of the repository holding the fonds. Preferably, but not necessarily ISIL. |
| country | Name of the country where the repository is. In English. |
facetFields
This respsonse parameter gives an enumeration of facets. Every facet has three variables.
| id | Internal APE identifier of the value. Use this "id" in the filter request parameter. |
| name | Human readable value (in English). |
| frequency | The number of results of this facet containing the searchterm. |
facets
| country | Name of the country where the repository is. In English. |
| subject | Subject that is added to the archival description |
| repository | Name of the repository holding the fonds |
| docType | Type of archives describing document where the result is found : "fa" for Finding Aid, "hg" for Holdings Guide or "sg" for Source Guide. |
| level | Type of result: "archdesc" for highest level description or "clevel" for subordinate components |
| hasDigitalObject | TRUE/FALSE |
| digitalObjectType | Type of the Object: most of the time: IMAGE |
| unitDateType | Type of date describing the archival unit. |
date facets
With the date facets you can zoom in on the period of time. Results are grouped in periods of two centuries in the first step. If you use these groupings in the request-parameter dateFilter, you'll have new dateFacets that groups the results into groups of two decads
| fromDate | Grouping of the search result in starting dates. |
| toDate | Grouping of the search result in ending dates. |
