The ESS Bibliography contains information about publications based on the cross-national European Social Survey. This includes analysis of ESS data, ESS methodology research and descriptions and documentation of the ESS
The ESS Bibliography utilises the powerful open source search engine Apache Lucene, which provides a rich query syntax:
A basic query consists of one or more simple terms. A term may be a single word or a phrase enclosed by double quotes. Multiple terms may
be combined using the boolean operators
- To search for entries containing both "values" and "participation" use the query:
- To search for entries containing either "values" or "participation" use the query:
values OR participation
- To search for entries containing the phrase "common values" use the query:
- To search for entries containing "common values", but not "participation" use the query:
"common values" NOT participation
You can specify a field for each term. There are three searchable fields in the ESS bibliography:
- To search for publications written by Shakespeare with "Henry" in the title use the query:
Note: The field is only valid for the term that it directly precedes, so the query
title_eng:Do it right will only find "Do" in the title field.
title_eng:"Do it right" matches the whole phrase.
Lucene supports single and multiple character wildcard searches. To perform a single character wildcard search use the "?" symbol. To perform a multiple character wildcard search use the "*" symbol.
- 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 query:
- Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the query:
Note: You cannot use a * or ? symbol as the first character of a search.
Lucene also provides advanced schemes like fuzzy search, proximity search and range search. Learn more here
