I used a locally sensitive minimum Hashi signature method for document retrieval. The design uses a collection of ideas, because it is to find a similar document in a folder, decided to use shingling to represent a document, using K-shingles technology, a document as a string of any length is k-shingle in this document as a string of K, in before processing will remove punctuation, unnecessary document spaces and newlines. For the value of K, if the general document is 5 enough, if the document is longer, it is relatively safe to take 9.
