11. A process comprising: receiving, into a computer processor, from a user a first search query comprising search criteria; executing in the computer processor the first search query to retrieve information relating to members of the business networking system based on the search criteria and to retrieve additional information relating to one or more facet values of the business networking system based on the search criteria and a scoring of a relevance of the facet values to the user; executing in the computer processor a second search query using the one or more retrieved facet values to determine a count of documents that satisfy the search criteria and that include the one or more facet values; selecting using the computer processor a portion of the facet values for transmission to the user; displaying on a user device the information relating to the members, the one or more facet values, and the counts for the one or more facet values; generating one or more posting lists, each posting list comprising documents having a particular facet value; terminating the second search query prior to completion of the second search query; and estimating the count for each of the facet values; wherein the estimating comprises multiplying a total number of documents in a particular posting list by a number of documents retrieved from the particular posting list that satisfy the search criteria at the time of the termination of the second search query, thereby generating a result, and dividing the result by an ordered position in the particular posting list of a last retrieved document in the particular posting list that satisfies the search criteria.

The process of claim 11 , wherein the count is estimated by a statistical approximation; and wherein the statistical approximation comprises an exponential regression or a polynomial regression.
