To search on particular fields, enter in the search box the field name followed by a colon followed by the search term (e.g. exampleField:exampleTerm). Search field names must be entered exactly as shown in order for the search to work.

Field labels are listed as they appear on the pages shipped with ICA-AtoM. If your administrator has customized the field labels in your ICA-AtoM application, these may be different from what appears on your page.

Searching date ranges

  • startDate:[YYYYMMDD TO YYYYMMDD]
    • This will search for start dates between the two dates listed, inclusive.
  • endDate:{YYYYMMDD TO YYYYMMDD}
    • This will search for end dates between the two dates listed, exclusive.
  • date:[1974 TO 1984]
    • This will search for textual dates (including uncertain dates) between 1974 and 1984, inclusive. Note: because this date data is not structured, the results may be vary due to inconsistencies in formatting.

In ICA-AtoM 1.4 the "date:" selector only searches on the textual "date" field, not the ISO formatted start/end date fields, so:

  • date:[1995-01-01 TO 1997-12-31] - "Range query boundary terms must be non-multiple word terms"
    • The hyphen is messing Zend Search Lucene, this type of date search will NOT work.
  • date:[19950101 TO 19971231]
    • This is searching for string values between 19950101 and 19971231 in the date field only. This query format is best suited to searching the start/end date fields which are formatted as YYYYMMDD in the search index.
  • date: [200-?]
    • This type of searching will be problematic, as the search index cannot determine non-specific dates. If the search needs to be exact, Users are encouraged to search using start date and end date with consistent formatting.
