Methods and systems are provided for matching expressions to data items. One exemplary method involves identifying a subset of expressions that match data items collectively and then identifying individual data items that match expressions of the subset. In one embodiment, the data items are partitioned into data item subsets, and further subsets of expressions collectively matching the data item subsets are identified. Data items of a respective data item subset are then individually matched to expressions of the respective expression subset that collectively matched that respective data item subset.
