This paper presents the vector retrieval modeling using the partial match pattern for text-rich YML documents. The vector representation of the tree of text-rich XML documents and sub-documents and the tree of queries and sub-queries are decribed. The partial match pattern is mapping from the relations of ancestors and descendants for a query to the relations of ancestors and descendants for documents.The paper calculates the similarity in the processing of the partial match.The results of experiemental analyses with different collections and queries show that it is effective in the completeness search and the precision search.
