Using Cts Query to Retrieve Collections Associated with the Given Document Uri- Marklogic

A few options come to mind:

Option One: Use cts:values()

cts:values(cts:collection-reference())

If you check out the documentation, you will see that you can also restrict this to certain fragments by passing a query as one of the parameters.

**Update: [11-10-2017] The comment attached to this asked for a sample of restricting the results of cts:values() to a single document(for practical purposes, I will say fragment == document)

The documentation for cts:values explains this. It is the 4th parameter - a query to restrict the results. Get to know this pattern as it is part of many features of MarkLogic. It is your friend. The query I would use for this problem statement would be a cts:document-query();

An Example:

cts:values(
  cts:collection-reference(), 
  (), 
  (), 
  cts:document-query('/path/to/my/document')
)

Full Example:

cts:search(
    collection(),
    cts:collection-query(
        cts:values(
          cts:collection-reference(), 
          (), 
          (), 
          cts:document-query('/path/to/my/document')
       )
    )
)[1 to 10]

Option two: use cts:collection-match()
Need more control over returning just some of the collections from a document, then use cts:colection-match(). Like the first option, you can restrict the results to just some fragments. However, it has the benefit of having an option for a pattern.

Attention:
They both return a sequence - perfect for feeding into other parts of your query. However, under the hood, I believe they work differently. The second option is run against a lexicon. The larger the list of unique collection names and the more complex your pattern match, the longer for resolution. I use collection-match in projects. However, I usually use it when I can limit the possible choices by restricting the results to a smaller number of documents.
