In the 'Advanced search' tab, you can specify whether you want to search in different specific metadata fields. These include:

  • Title
  • Author
  • Original Identifiers
  • Sender
  • Text
  • Publication date
  • Period
  • Provider
  • Dataset
  • Edition
  • Volume
  • Issue
  • Genre
  • Retweets
  • Label
  • Documenttype
An overview of current integrations with data providers can be found here. The collection registry gives a full overview of available datasets can be found in the Collection registry.

The second field in the Advanced Search tab allows you to specify if you want iCANDID to search for results that contain the words you typed by selecting 'Contains one of the words'. The option 'Contains the exact phrase' will give you search results in which the phrase exactly as you typed it appear. By selecting 'Starts with' you will not only search for the entered term, but also for words that start with that letter combination. For example, searching for 'parliament' with 'starts with' will also return articles with the term 'parliamentary'.

With the ' ' symbol you can add lines to enter more search terms and the '' symbol removes that line.

Lines are grouped with an operator (and/or) :


You can change the operator by clicking it (‘and’ becomes ‘or’ and vice versa)
With the ‘’ symbol you can add new group. This allows for more complex search queries.

The example below is a search for records containing either of the words ‘fire’ or ‘water’ in the title and with genre being ‘Drama’ or ‘Mystery’


Boolean search

This is the most powerful way to do searches on iCandid. However it is also the most complex and should only be used by users who absolutely need this functionality. If this is the case, you can contact icandid@kuleuven.be to request the activation of this function.

Ex. :

 (name.@value:”fire” OR name.@value:”water” ) AND (genre.@value:”Drama” OR genre.@value:”Mystery”)

Syntax

A query should always consist of a field to search in and a value to search for.
So, if you wish to search for a record with word ‘fire’ in the field ‘name.@value’ you should write  name.@value:”fire”


Below is a list of available fields to search in. More information on these can be found at https://icandid.libis.be/_docs

You can use wildcards in your search queries:
  • The single character wildcard search looks for terms that match that with the single character replaced. For example, to search for "text" or "test" you can use the search: te?t
  • Multiple character wildcard searches look for 0 or more characters. For example, to search for test, tests or tester, you can use the search: test*
  • You can also use this in the middle of a word: te*t
For the Date and Number fields there is the option to search in a range:
  • review.dateCreated:[2010-11-05 TO 2023-04-03] will find records with the field review.dateCreated set to a date between 05-11-2010 and 03-04-2023.
  • You can also use a wildcard here : review.dateCreated:[2010-11-05 TO *] will find records with the field review.dateCreated set to a date after 05-11-2010.
  • For numbers use associatedMedia.height:[100 TO 600]

Be aware: the ‘TO’ needs to be capitalized. So ‘to’ will result in an error.


Operators

Queries can be combined with the operators AND, OR and NOT.

Ex.

 name.@value:”fire*” AND NOT name.@value:”firetruck”
will find records with the name.@value containing a word starting with ‘fire’ but that don’t contain the word ‘firetruck’.

Be aware: the ‘AND’, ‘OR’ and ‘NOT’ need to be capitalized. So ‘or’ will result in an error.


Grouping

Queries can also be grouped by using brackets.

Ex.

 (name.@value:”fire” OR name.@value:”water” ) AND (genre.@value:”Drama” OR genre.@value:”Mystery”)
is a search for records containing either of the words ‘fire’ or ‘water’ in the field name.@value and with genre.@value containing ‘Drama’ or ‘Mystery’.

Additional filtering

In addition to the search query, you can filter based on the date of publication by using the From: and ‘to and including’ filters. You can also select which datasets need to be queried.
