Title: Smartlist syntax - AND/OR
Post by: strebormj on February 07, 2009, 08:58:17 am

I have tracks with myriad Genre values like "Alt Rock," "Alternative Rock," "New Rock," "Nu Rock," etc., that I would like to include in a smartlist.   There doesn't seem to be a way to OR together values of a [Genre] [Contains] rule, and there doesn't appear to be a guide on how to use a contains-type function in a [Custom] rule. 

What's the best way to implement < Genre.Contains("rock") || Genre.Contains("alt") >?

Thanks

([Genre]="alt" or [Genre]="rock")

Your example matches complete strings, not substrings, correct?  I'm looking to match substrings, which means either using wildcards or contains() I think.

Thanks for the link to the page on grouping rules, however.

It looks like

Custom (
Genre contains "alt"
Genre contains "rock"
Custom )


might be the way to do it, although after doing that, the dialog seems to screw up the paren and bracket symbols.  Doing what I did above results in the grouping being lost and the logic being switched to (Genre.Contains("rock") AND Genre.Contains("alt")).

My example should match substrings...

Hmm.  That does work.  When I close the dialog and reopen it, it creates the grouping correctly.


Thanks for the tip.

Do you know how to handle negation (e.g., ([Genre]="alt" or [Genre]="rock" AND [Genre]<>"classic")?  Apparently it's not "!=" or "<>" or "!([Genre]=...").

To negate, put a - in front of the expression, eg

-[genre]="rock"

will show all genres that do not contain "rock"

Thanks again, Mark.

You should try using the Wizard to create expressions, it's much easier to begin with.  You can then see the text version by clicking on import/export in the wizard.

To access the wizard in the search field, click the down arrow.

Cheers,
