In this report, we formalize a problem of associative search in terms of formal concepts. First of all, we define a notion of aspects as intermediate bridge concepts connecting initial concepts and target concepts. The target concepts, considered as drifted versions of the initial ones, must be conditionally similar to the initial ones with respect to the bride concepts. In order to find such target concepts effectively, we present a concept search procedure accessing two kinds of incident relations. One relation describes a person-feature relation, and contributes for suggesting potential persons related to the bridge concepts. On the other hand, the second type relation defines standard concepts of document-feature relations based on which the target concepts are derived under a similarity constraint given by the intents of bridge concepts.
