I need to export all the documents from the database except documents from specific collection.

Let's say, I have a collections called test1 (100 docs), test2 (200 docs) and test3 (100 docs)

As per my requirement, I want to export all the documents from test1 and test2 collection and not from test3 collections.

Is it possible to do this using MLCP ?

I would apply a -query_filter with a cts:and-not-query() specifying the positive and negative cts:collection-query() queries.

cts:and-not-query(
 cts:collection-query(("test1","test2")),
 cts:collection-query("test3")
)

-query_filter parameter value is the query serialized as either XML or JSON

As XML:

<cts:and-not-query xmlns:cts="http://marklogic.com/cts">
  <cts:positive>
    <cts:collection-query>
      <cts:uri>test1</cts:uri>
      <cts:uri>test2</cts:uri>
    </cts:collection-query>
  </cts:positive>
  <cts:negative>
    <cts:collection-query>
      <cts:uri>test3</cts:uri>
    </cts:collection-query>
  </cts:negative>
</cts:and-not-query>

as JSON:

{"andNotQuery":{"positiveQuery":{"collectionQuery":{"uris":["test1", "test2"]}}, "negativeQuery":{"collectionQuery":{"uris":["test3"]}}}}
