Field help (RECHERCHE)

This screen is used to define a search criterion or a selection filter on a table.
Depending on the context, the table is imposed or it is possible for the user to select it themselves.
The criterion or the filter will be composed by combining lines from the grid according to a logical "and".
Each line defines a comparison operation under the form: Operator field Field value being any field from the table Operator being one of the following: = , < , > , <= , >= , different from, template (this operator checks the compliance of the field with respect to a template using the wildcards * and ?) Value being the comparison value.
