I'm watching to see if ML has an opinion on your () vs. cts:query(())
question! 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.

Hi Shannon,
Thanks, and yes, I like the modularized approach too!

withconditional logic
Hi, Tim,
I've always had great results using simply the empty sequence. 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,

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?
Thanks again,
Tim
