Search in MarkLogic

Remarks#

This section provides an overview of search in MarkLogic. Intent is to cover cts:search, search:search and qbe with use cases and examples

Fetching all the documents with word “marklogic”

cts:search(
    fn:doc(), 
    cts:word-query("marklogic"))

Fetching all the documents with word “marklogic”, document in collection “first-collection”

This can be done in the following two ways -

cts:search(
    fn:collection("first-collection"), 
    cts:word-query("marklogic"))

In this, the scope is changed from all the documents to documents in collection “first-collection” only.

In the second approach, use of cts:collection-query has been made. This should give better performance than the first approach.

cts:search(
    fn:doc(), 
    cts:and-query((
        cts:collection-query("first-collection"),
        cts:word-query("marklogic")))

Fetching all the documents with a particular value of an element

This query returns all the documents with element “company” and its value as “marklogic”

cts:element-value-query(xs:QName('company'), 'marklogic'))

Checking presence of elements and attributes in documents

The following query returns the documents which have an element named “company” -

cts:element-value-query(
xs:QName('company'), '*', ("wildcarded")))

The following query returns the documents which have an element named “company” with an attribute named “name” -

cts:element-attribute-value-query(
xs:QName('company'), xs:QName('name'), '*', ("wildcarded")))
