8. A computerized method, implemented at a processing unit of a computing device, for manipulating a composition of a list of terms associated with a query class, the method comprising: extracting a list of terms, wherein each term in the list of terms is associated with a search refinement path of a query; scanning a searchable database to identify at least one of equivalences between terms within the list of terms and a set of relevant terms that share a common categorization with the query, wherein terms in the list of terms are derived from past searches or are modifiers of past searches, and wherein relevant terms are identified based on scores assigned to one or more topics which indicates the relevance of the relationship between the topics that categorize the gallery of entities assembled to form the query class and the terms in the list of terms; condensing or expanding the composition of the list of terms by applying the equivalences or the set of relevant terms, respectively, to generate an updated list of terms; replacing the list of terms with the updated list of terms; and writing the updated list of terms, in association with the query class, wherein the query class comprises a collection of similarly themed queries previously received from one or more users, to a storage location on computer-storage media accessible by the processing unit of the computing device.
