And when you do the cts:highlight, you typically do it on a subset of the
results (the first page, for example) so that you do not need to get every
result from your search, which as you said, would be expensive. So the
psuedo-code is something like:
let $query := "hello"
for $res in cts:search(collection(), $query)[1 to 10]
return
cts:highlight($res, $query, <b>{$cts:text}</b>)
The Search API (search:search, for example) does a lot of this for you, so you
might want to look into that for a more complete solution.

If I understood you right, what you want is:
let $query := cts:word-query ("ADENOHYPOPHYSEAL HORMONES", "GROWTH", ...)
for $result in cts:search ( , $query)
return cts:highlight ($result, $query, <match>$cts:text</match>)
and then arrange for <match> nodes to be highlighted in your output?
You'd guest a list of (whatever you searched for - documents?) with the
highlighting applied...
I'm confused because you seem to have already written that almost, so maybe I'm
missing something?
maybe what you're looking for is more consolidated output like:
return <result uri="{base-uri($result)}">{cts:highlight ( ... ) //
hit}</result> ?

This is a refinement on the question I asked the other day. I'm getting
better at formulating my questions so maybe the advise might be closer :)
Suppose I do a query and get a XML document which has a field that has text
that looks like this :
"The anterior glandular lobe of the pituitary gland, also known as the
adenohypophysis. It secretes the ADENOHYPOPHYSEAL HORMONES that regulate vital
functions such as GROWTH; METABOLISM; and REPRODUCTION."
Those things in all upper case are likely terms that exist in other documents.
What I'd like to do is to do a search for each of those terms across the entire
DB, and if found, create links to either the highest scored find, or to a
results page (either will do).
I've poked around and found many little things that are part of a possible
solution, but nothing that does exactly what I want.
For example: cts:hilight() could be used to add the links to the words.
and I could find a consolidated result set by using
cts:search( ... , cts:word-query ( fn:tokenize(phrase) ) )
to find all matches etc. I an easily get all the upper case words and create
a search.
But my problem is this. Suppose I create a search on all the upper case words
("ADENOHYPOPHYSEAL" , "GROWTH" , "METABOLISM")
and get a result back with cts:search()
How can I match up Which nodes of the result matched which word so I can
hilight them ?
e.g if I did
for $result in cts:search( ..... all the words )
// Which word did $result match ???
My only thing I can think of is that i would have to iteratively loop through
the terms and do a search one by one.
for $word in ( big oh list of search words )
for $result in cts:search( ... , $word )
cts:hilight( $phrase , $word , { link the word } )
My guess is that this will perform horribly. I'd rather get a single
consolidated search then do some magic like
for $result in cts:search( ... , all the words )
cts:hilight( $phrase , the word that matched $result )
Does this make any sense ? Is there an API or design pattern to do this ? Or
should I do the outer loop instead ?
I looked at cts:walk but it looked like it to use it for this would still
involve looping on the cts:search() for each term matched.
Thanks for any advise.
