Using Phrasea engine involves typing the fields of the Phraseanet base format.
Three types are available:
The fields contents are indexed by value, as they are. This type is best used for exact searches (“author=William Shakespeare”) or fuzzy. Note that only the first 32 000 characters will be used for indexing.
The content are interpreted as a number. This type allows searches with relational operators (width>1000) or sorting by numerical value (for example, by filesize).
The expected content is an iso date format, eventually incomplete (for example : 2009). This formatting allows comparisons on dates (“date>=2000 and date<2012/12/20”) or sorting by date. When a field has a DATE format, a calendar assists the typing of a date in edition form.
