The modularization is a clever idea. I appreciated your mentioning it.

As to the modularized approach, I realize your example didn't call for it, and you're probably already using that strategy in your production code, but I thought I'd mention it in case it would help somebody watching the discussion.

I'd be interested to know if there is any advantage to using cts:query(()). Also, since this is not reflected in your example, just in case, I'd like to suggest modularizing it a bit, for far easier reading and maintenance--After initializing your variables with a series of a let assignments, create a combined cts:query by calling other functions, like so: let $combined-query := cts:and-query(( if ($foo) then search:qry1(...) else (), if ($bar) then search:qry2(...) else (), ... )) The search:qry* functions would return a cts:query type -- basically breaking down each field or fieldset of your form, or some other logical grouping, into separate functions. Then call cts:search(input(), cts:combined-query) Best, On Jun 1, 2009, at 3:02 PM, Tim Meagher wrote: Hi Folks, Is there a preferred way to build a series of cts:search constructor functions when using conditional (and/or) logic? In the following example I insert a cts:query() if an value is blank, in the other I insert an empty sequence: cts:search( //Record, cts:and-query (( if ($publisher ne "") then cts:element-value-query(xs:QName("Publisher"), $publisher, ("case-insensitive", "diacritic-insensitive", "punctuation-insensitive") ) else cts:query(), if ($title ne "") then cts:element-value-query(xs:QName("Title"), $title, ("case-insensitive", "diacritic-insensitive", "punctuation-insensitive") ) else () )) ) Is there a rule for using cts:query() or the empty sequence () for dynamically building cts:search constructors?
