    • A method and apparatus are disclosed for ranking the results of a document search by identifying a prior, similar search and assigning a weight to each document based on whether the document was selected by a user of the prior search. The assigned weights are utilized to rank the documents identified by the document search in order of their relevance to the search terms. The search terms of the document search and information describing the selections made by a user of the document search are then stored to facilitate the assignment of weights to documents in future searches. According to another aspect of the invention, the weight assigned to a document is correlated to a degree of closeness of search terms of a prior search and search terms of a new document search. For example, a degree of closeness measurement is defined that correlates to a number of synonyms common between the search terms of a prior search and the search terms of a new document search.
