Rahul,
The fn:doc function takes a URI (a string), but in your second case you are
passing it whatever is selected by the XPath /documents/book2-which is most
likely an empty sequence, which is automatically cast to an empty string. If
the URI of your document is really /documents/book2, then you need to put that
inside quotes (either single or double will work), thus:
fn:doc("/documents/book2")//book/@year=2002. My guess is that the URI is
actually /documents/book2.xml, in which case the ".xml" must be included inside
the quotes: fn:doc("/documents/book2.xml")//book/@year=2002.
Basically, a URI is a string, not an XPath, so when you enter one manually you
must enclose it in quotes.

Subject: [MarkLogic Dev General] Difference between two queries
hello all,
i am in a flux to understand whats the difference between following two queries
fn:doc(xdmp:node-uri(
cts:search(//books,cts:and-query((cts:element-word-query(xs:QName("title"),"human"
, ("wildcarded", "case-insensitive")),cts:element-word-query
(
xs:QName("status"),"Unavai* " ,
("wildcarded", "case-insensitive")
)
))
)))//book/@year=2002
returns TRUE
AND
fn:doc(/documents/book2)//book/@year=2002
Returns FALSE
Argument to first query also returns the uri of document which satisfies the
search criteria whereas when i pass this Uri by myself it returns false.
please reply.
regards
Rahul Saluja
