A fuzzy, or ambiguous, keyword searching process and systems for implementing the fuzzy keyword searching process are provided. In general, one or more keyword search terms are first identified for a search. Next, a user is enabled to adjust a logical fuzziness, or logical ambiguity, for each of the one or more keyword search terms. As used herein, logical fuzziness of a keyword search term refers to the extent to which associated keywords are considered for the search. In one embodiment, the user may also be enabled to view and adjust keyword associations for each of the keyword search terms. A search is then performed based on the one or more keyword search terms and the logical fuzziness of the one or more keyword search terms, and results of the search are presented to the user.
