Ningjun,
I believe you want to use a cts:document-query() with the thousands of URI's to
constrain your search. Set this as an <additional-query> in search:search().
That's if your restriction is on the MarkLogic URIs for each document. If you
actually have URL's encoded in the documents in a <url> element or similar, use
cts:element-value-query(xs:QName("url"), $doc-urls) as the additional query.
Yours,
Damon

Subject: [MarkLogic Dev General] How to do keyword search within a set of
dicuments returned by some function.
We have a requirement to do keyword search on a set of documents returned by
some function. For example the function getRelatedDocUrls() return a list of
document URLs (could be hundreds of thousands of document). I need to do a
keyword search within those documents and return the correct total count and
return result with 10 documents per page. What is the most efficient way to do
that?
One option I am thinking is to do the keyword search first then join the result
with the set of documents, e.g.
Let $urls := getRelatedDocUrls()
for $result in search:search(keyword)/search:result, $url in $urls
where $result/@uri = $url
There are two problems
1. search:search(keyword) return one page at a time. Suppose I make it
return 20 docs per page, then the first page may not have any document matching
$urls.
2. search:search(keyword) return the total count of document matching
keyword. However I want the total count of documents not only matching the
keyword, but also with url in $urls
Of course I can make search:search(keyword) to return all result in one page
and then through the join to find out the answer above. However this will be
very inefficient because search:search(keyword) can return millions of
documents. I just want the correct total count and the first 10 documents that
match the keyword and with url match $urls.
What is the most efficient way to do this?
Thanks
