cts:document-fragment-query( $query as cts:query ) as cts:document-fragment-query
Summary
Returns a query that matches all documents where $query matches
any document fragment. When searching documents, document-properties, or
document-locks, this function provides a
convenient way to additionally constrain the search against any document
fragment.
| Parameters | |
|---|---|
| query | A query to be matched against any document fragment. |
Usage Notes
A document fragment query enables you to cross fragment boundaries in an AND query, as shown in the second example below.
Example
cts:search(
xdmp:document-properties(),
cts:document-fragment-query(
cts:word-query("hello")))
(: All properties documents whose corresponding document
: (that is, the document at the same URI as the
: proerties document) contain the word "hello". :)
Example
xquery version "1.0-ml";
(:
Given a document with a fragment root of <fragment>
created as follows:
xdmp:document-insert("fragmented.xml",
<root>
<author>bob</author>
<fragment>dog</fragment>
<fragment>cat</fragment>
<fragment>fish</fragment>
</root>);
:)
cts:search(fn:doc("fragmented.xml"),
cts:and-query((
cts:document-fragment-query("bob"),
"dog"
))
)
(: returns the fragmented.xml document :)
