MATCHRECURSE

The MATCHRECURSE field specifier matches documents containing a specified reference in a ReferenceMemoryMappedType field recursively to a maximum number of times. This field specifier must be restricted to a single ReferenceMemoryMappedType field.

Format

FieldText=MATCHRECURSE{Ref,RecurseNumber}:YourField
Ref The initial reference. The matching is case-independent.
RecurseNumber The maximum number of times to recursively return references using the value of the ReferenceMemoryMappedType field.
yourField The name of the ReferenceMemoryMappedType field.

Example

For example:

In this example, PARENT is a ReferenceMemoryMappedType field. The query

action=query&fieldtext=MATCHRECURSE{MyRef,1}:PARENT

matches the document with reference MyRef (parent) and documents whose PARENT field contains MyRef (children). The query

action=query&fieldtext=MATCHRECURSE{MyRef,2}:PARENT

matches the document with reference MyRef (parent), documents whose PARENT field contains MyRef (children), and documents whose PARENT field contains the references in the returned child documents (grandchildren).
