But how does it actually work? Find here good tips on how to search and on Advanced Search features.

1) Searcable Fields

Definitions of Searchable ETB Fields

  • Topic: the substantive content of a resource.
    Searcable by the ETB Thesaurus descriptors:
    • Simple Search: yes
    • Advanced Search: yes
  • Age range: the age range of the audience to whom the resource is intended.
    Searcable by the ETB controlled age level list
    • Simple Search: no
    • Advanced Search: yes


  • Target audience: the typology of audience to whom the resource is intended.
    Searcable by the ETB controlled target audience list
    • Simple Search: no
    • Advanced Search: yes


  • Description: a brief informative description of the document contents.
    Searcable by: key words (any word that appears anywhere in the document).
    • Simple Search: yes
    • Advanced Search: no


  • Title: the title of the resource.
    Searcable by the key words (any word that appears anywhere in the document).
    • Simple Search: yes
    • Advanced Search: no
2) General Notes
  • Search is not case sensitive.

  • Stemming is not possible (i.e.: histor*).

  • Even if you make your query in one language, you will get the results also in other languages.

  • You can search by one uni- or compound term.
    If you include the search term in quotation marks, that means that you want an exact correspondence.
    • Without quotation marks, the system will consider the search term also as a part of a compound term.

Example: 1. animal

2. wild animal
3. "animal"
4. "wild animal"

A search by animal retrieves:

[English ] animal (8)
[ French ] animal domestique
[ Spanish ] animal doméstico
[ English ] domestic animal
[ English ] wild animal (6)
[ Spanish ] animal salvaje (6)
[ Spanish ] animal (8)
[ French ] animal (8)
[ French ] animal sauvage (6)

A search by "animal" retrieves:

[ English ] animal (8)
[ French ] animal (8)
[ Spanish ] animal (8)

In case you want to search for more than one term or term combination (i.e. "wild animal" + "Europe") use our Advanced Search modality.

4) Advanced Search - Help

How to Search?

The Advanced Search is possible only by thesaurus terms.

  • You have already chosen the language you want to use within [Preferences].

  • Now, you have two possibilities:

    1. using the [look up] field by browsing the thesaurus;
    To add terms to your query, click on the check box(es) next to the desired term(s) and then scroll to the bottom and click on an [Add to Set x] button.
    • Push a [Submit to xx] button to start your search.

    2. using sets, inputting descriptors directly.

5) Tips for Successful ETB Searching

Simple strategies can help you in getting exactly what you are looking for:

  • Use pre-coordinate descriptors whenever possible.
    Before submitting your search, a quick browsing in the thesaurus might help you in identifying the right descriptor. For example, if you are interested in "working mother" and you get no results, before trying post-coordination (that is "woman" AND "labour"), a quick browsing of the thesaurus would display the more adequate descriptor "women's work".

  • Do not exaggerate with the use of descriptors concerning secondary topics or secondary aspects of a complex topic. Remember that secondary or minor topics are often inconsistency processed, given the lack of an indexing syntax (see example below).

  • Avoid too ambiguous modular combinations (AND operator). The suggested combination number for getting the most pertinent answers is from 2 to 5 descriptors.

  • In a search string like: "educational policy", "access to education", "woman", "immigrant", "language policy", "public school", "private school", "history", how can we tell whether "access to education" concerns women, immigrants or both?
    Are immigrants concerned only by "language policy"? And whom does the descriptor "history" concern?
    The document will be retrieved both by someone interested in the history of private school and by someone interested in the history of women.
    Thus, use condensed and meaningful strings.
