Help about search
Every search action implies the execution of a query on the whole set of records in dat@UBFC.
A query to dat@UBFC is interpreted as a logical expression. This query may be formulated in the search bar thanks to a query language, presented below.
All records satisfying the query condition are displayed. It is then possible to refine the query thanks to facet search (accessible on the left) by checking further criteria which will be added to the initial query.
Starting a search
Full text search: the condition is simply composed of one or several words. These words are searched in all fields of all records.
Selector search: a selector may be used to search a word in a definite field. These fields correspond to elements of metadata profile.
Multi-criteria search: full text or selector search criteria may be combined using logical operators.
Using logical operators
The “and” operator is indicated by the “&” symbol. This operator is used by default when no operator is specified. As in mathematics, the “and” operator has priority upon the “or” operator.
The “or” operator is indicated by the “;” and “|” symbols (the latter is the “pipe” symbol, not the uppercase “i” character).
The “not” operator is indicated by the “!” symbol. It allows negating a condition. For example, specifying “astronomy” returns all records with the word “astronomy”in a field; specifying “!astronomy” returns all records without the word “astronomy” in any of their fields.
Parenthesis may be used to constrain the order of operations with the same conventions than in mathematics.
Full text search
It is possible to search for one or several words in the whole set of fields of the data base. The search is performed independently of the word number (singular or plural) for words which have a plural with an -s suffix. When results of the query are displayed, exact occurrences are highlighted using a different colour for each searched word.
A selector can be used to search for a word in a given field. These fields correspond to elements in the metadata profile.
The format of the query is: selector_name:value
It is a common use to surround the value with quotes to avoid the use of escape characters. Some among the selectors have shorter-form synonyms.
Selection on data access type.
Possible values are “open” or “restricted” when one needs to get in touch with the contact person to possibly gain access to the data.

When values used in search criteria contain spaces or special characters, then these need to be escaped.
A string of alphanumeric characters can be supplied “as is”. It is possible to surround a text containing characters such as spaces using simple (') or double (") quotes. To prevent the interpretation of a special character, it is possible to insert the escaping character "\" in front of it.
In the following cases, using an escaping character is mandatory:
|Character||Escaped character||No surroundings||Surrounded by single quote (')||Surrounded by double apostrophe (")|
|New line *||\n||X||X||X|
*: not usable with most search criteria
Plain text searches are usable only for words.
Some examples of escaping:
Escaping of the space and colon characters:
Escaping the space, parenthesis and single quote characters:
