Basic principles for OpenBibArt search

Enter one or more words to start your search

You can narrow down the number of results by choosing an additional criteria in "Refine your search"

Start a new search by selecting a hyperlinked word in either the list of results or in the record display

In the latter case the number of hits may be superior to the result of the initial search.

Using the search engine (Exalead)

The implicit operator used on Exalead between different words typed in the same field is “AND”.

The default operator between the different fields in an advanced search is also “AND” (by default).

1. Syntax

" (quotation marks)
to run an exact search in a field, you need to enter the words between quotation marks. However please note that the search carried out will not be a truly exact search because the search engine will take out all the “stop words” (such as 'a,' 'the,' and 'in'). However this type of search also excludes all documents which contain the search terms specified but not in the correct order or one after the other.
e.g.: action painting will find records with the words action and painting, whereas "action painting" will find records with the exact term
* (Truncation)
an asterisk placed at the end of a term – or after the first letters of a word – runs a search on all words beginning with... the term or first letters. This can be used to search for singular and/or plural forms of a term.
e.g.: palette* will find palette, palettes
+ (plus)
this can be used to run an exact search for the term after this operator.
e.g.: entering  +repentir  will search for all documents which contain the exact word repentir and will ignore the singular form windmill. The + operator can also be used to run a search which includes linking words (such as the, a, of, or, and) which are ignored with the default search.
- (minus)
excludes certain terms from a search.
e.g.: French impressionism –Caillebote: this will search for all documents which contain the phrase French impressionism but do not contain the word Caillebote.

2. Operators

searches for all documents which contain both terms.
e.g.: art nouveau AND Nancy: this search will return documents containing the phrase art nouveau and the word Nancy
searches for documents using more advanced logic.
e.g.: art nouveau OR Jugenstyle: this search will return all documents containing the phrase art nouveau or the word Jugenstyle.
excludes a term or phrase from the search.
e.g.: art nouveau NOT Nancy: this search will return all documents containing the phrase art nouveau but which do not contain the word Nancy.
searches for documents in which the terms entered are, by default, within sixteen words of one another in the text.
this operator can be used to specify the maximum distance between two search terms.
e.g.: art NEAR/5 nouveau: this will return all documents in which art is found at most five words away from nouveau.
can be used to search for documents created before or after a specified date.
e.g.: cubisme BEFORE 2004: returns all documents published before 2004.
this operator can be used to run a search for optional words. If these are not included in a document, the document will still be displayed in the results list. All documents containing the word after OPT will be displayed first on the list but those documents which do not include the word after OPT will still be displayed.
e.g.: art nouveau OPT Nancy: this search will return all the documents containing both art nouveau and Nancy  first, and then all documents which only contain art nouveau.

3. Specific operators

this operator allows to search based on phonetic spelling
e.g.: soundslike:exaleed
this operator can be used for a search with an approximate spelling
 e.g.:  spellslike:exlaead
Logical expression
Exalead allows you to search for multiple words and exclude other words.
e.g.: ((bleu OR gris) AND NOT ciel)
Regular expression
it is possible to search using regular expressions. Regular expressions are introduced by the character '/'. Inside a regular expression, the point ('.') can be used in place of any character, the '*' is used to specify a repetition of character. '|' means 'or ' and parentheses can be used to group characters. Regular expressions can be used to specify with great precision a fuzzy set of terms.
e.g.: /mpg(1|2|3)?/ finds mpg1, mpg2, mpg3.
e.g.: /gr.y/ finds gray and grey

4. Advanced Research

Exalead allows searching by field / specific index.

The following syntaxe must be used: research criteria in lower case, followed by a colon and the search term(s)

Runs a search on an individual author (person) or a corporate author (organization), a conference name or a university (thèsis)
e.g.: author:Smith
author:Université de Paris 10
[Field names in XML: dc.contributor.*,]
Runs a search in the words of an abstract (added from 1997 onwards)
e.g.: abstract:"Staël between 1943 and 1948"
[Field names in XML: dc.description.abstract et dc.description.abstractalt]
Allows to search by document type (controlled list) or by subtype (conference preprint; PhD thesis,…)
e.g.: type:thesis  - runs a search in the global category "thesis"
type:Ph.D  - returns only Ph.D theses
[Field names in XML: dc.type.none et dc.type.subtype]
Allows you to search by the title of the series or collection the item belongs to
e.g.: series:report
[Field names in XML: dc.relation.ispartofseries]
Runs a search in any field with an identifier(Report number, ISSN, ISBN, etc)
e.g.: identifier:ECRC-RR--79/1
[Field names in XML: dc.identifier.*]
Search classifications and standardized subject headings such as DDC or UDC or MeSH, etc. Please note that these fields are rarely filled in.
e.g.: subject:330.94
[Field names in XML: dc.subject.*]
Returns the commercial publisher of documents
e.g.: publisher:TextRelease
[Field names in XML: dc.publisher.none]
Returns items according to their country of origin. Enter either the ISO 2-caracter code or the English name of the country
e.g.: country:FR
[Field names in XML:]
