The listed filter is more complex "The *listed* filter operator returns the titles of the tiddlers that have list fields that contain any members of the current list. The optional operand can be used to specify a different field.". So: - you select a list of tiddlers, which are what you are searching in the list fields. Here: "french" and "A2" - you use the listed operator - optionnaly, you specify in operand the name of the list fields where you search the tiddlers of the current list. Here: "courses" for french and "levels" for A2.
You can see that the "courses" and "levels" operands (2 different fields) do not apply to the same selected list of tiddlers (2 lists of 1 tiddler: "french" and "A2"), that's why I said that the sources are different. And you can't append the two parts as you would do to AND two operators (AND is for 2 operators that applies to the same selected list of tiddlers, eg tag[aTag]has[aField]). You can't change the selected list of tiddlers between two operators without separating the two parts, and that results in an OR which is not what we want. The "+" allows to append operators to several selected lists of tiddlers (which is equivalent to an OR), but it is the same operator added to each list of tiddlers. It's a sort of factorization of an operator. If there is only one list of tiddlers, it is the same as an AND. It's not what we want. In fact, we want a sort a "least commun multiple" in two filter results. I may be wrong, but I fear this can't be currently solved without regexp (which allows to search for a string in the value of a field). Sorry if my explanation is not clear, I'm not fluent enough in English to clearly explain what is already difficult to think in French :-S -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
