1. A method comprising: for each ngram of a plurality of ngrams, determining a click entropy that represents an extent to which a plurality of clicks that occurs with respect to a plurality of search queries that include the ngram is diversified among a plurality of domains based on a proportion of the plurality of clicks that corresponds to each domain of the plurality of domains; comparing the click entropy for each ngram to an entropy threshold to determine a subset of the plurality of ngrams such that the click entropy of each ngram in the subset is less than the entropy threshold; determining that each ngram in the subset is associated with an intent to access a respective designated domain of the plurality of domains, the designated domain for each ngram in the subset corresponding to a relatively greater proportion of the plurality of clicks that occurs with respect to the plurality of search queries that include that ngram than others of the plurality of domains; and increasing a number of search results that correspond to the designated domain for a specified ngram from the subset that are to be provided in response to receipt of a search query that includes the specified ngram to be greater than a specified maximum number based on the specified ngram being associated with the intent to access the designated domain for the specified ngram.
