An efficient determination of a click distance value is made for each document in a corpus of documents from data included in a locally-stored inverted index. The click distance is measurement of the number clicks or user navigations from a first document on the network to another document. Specialized words are included in the locally-stored inverted index. The specialized words relate source documents to a set of target documents. A click distance is assigned to a source document when an inverted index is queried for the corresponding set of target documents according to a query that passes in one of the specialized words. The process is repeated for each document in the corpus of documents.
