Hi Geert,
Thanks for the tips!
For now I have achieved the majority of the functionality I need with a
string range index on paragraph and the following query:
for $val in cts:element-value-match(
xs:QName("paragraph"),
fn:concat("*", $q, "*"),
("item-frequency", "frequency-order", "limit=50", "collation=
http://marklogic.com/collation/codepoint";))
return <s:result count="{ cts:frequency($val) }" value="{ $val }"/>
This has the advantage of being very fast, but the downside is that I loose
MLs built-in language knowledge due to the pattern search.
I'll try your suggestion to see if I can get the same kind of performance
from the seach api.
Also this query returns values instead of the nodes, but I can use the value
to retrieve the node when the author picks one of the paragraphs for reuse.
Thanks all for the help!
Kind regards,
Laurens van den Oever

Just a quick pointer on this one. Be aware that searching is fragment-based.
That is the reason why it works so fast. The query you pass to cts:search is
applied to all fragments that cover the result of your searchable Xpath
expression. Just to prevent mistakes I always recommend my colleagues to use
something like this:
cts:search(doc(), cts:element-word-query(xs:QName("paragraph"),
$query))//paragraph
Instead of:
cts:search(//paragraph, cts:element-word-query(xs:QName("paragraph"),
$query))
To find the specific paragraphs that contain matches to your query, you will
have to use cts:highlight, and then use Xpath to find all paragraphs that
contain highlighted text..
Kind regards,
Geert
