A method and system for identifying assets in support of a transaction includes obtaining a set of filter values for a customer from each of a plurality of filtering entities. The filtering entities may provide rules, which may be executed in a distributed manner by remote systems, that generate filter values based on input data, or that generate customized filter rules based on the input data. Filter values are used to filter search results produced by a query of a database of assets. Where customized filter rules are generated, the rules are executed against the characteristics of the assets identified in response to the query in order to produce filter values, and the filter values are then used to filter the search results. The search results can be ranked according to a ranking value generated in advance of filtering in order to rank the assets in order of suitability.
