The claimed subject matter provides systems and/or techniques that effectuate combining domain-tuned search systems. The system can include mechanisms that obtain queries, written descriptions, or illustrative web-pages regarding a particular area of interest, and generate a definition related to the area of interest. The definition contains a list of paths with associated weights employed to identify an pre-established first domain-tuned search system related to the area of interest. The first domain-tuned search system thereafter can be combined with a second domain-tuned search system related to another area of interest and presented to a user for utilization in re-ranking generic search results to be specific to the first and second domains of interest if combined, or to only the first domain if weights for the second domain are logically subtracted.
