A per-subsearch setting for the hybrid-search 'limit' factors.
This structure is to be used to set different values for the vector and the lexical portions of the hybrid search.
Each of the attributes is a floating-point number, representing the multiplicative factor applied to a search final 'k' to calculate the "limit" value for the associated sub-search. For instance, if vector=1.5 and lexical=3.0, a hybrid search called by asking a final set of k=4 results will be executed with limits of 6 for vector and 12 for lexical. (The results are approximated to an integer.)
