Oracle ATG Web Commerce Search has a large number of parameters that control searching. To simplify the adjustment of these settings, Search provides five search strategies that implement sets of parameter values. The search strategy is selected by the following attribute:
<query strategy="strat"The strat can be one of the following five values:
everything– Try unlimited search, without any parameter values that can restrict the search algorithm; also try all term expansions during document candidate retrieval.expand– Try an expanded search, increasing the default parameter values that can restrict the search algorithm.normal– Default system settings, optimized for fast search with good search quality; this is the default value.restrict– Try a restricted search, decreasing the default parameter values which will further restrict the search algorithm; disable non-equal term expansions; adjust relevancy calculation to prefer literal matches.exact– Try an exact search, which is the same asrestrictplus a heavy increase in the/exactWgtsetting. This forces results to contain the literal query string.
If there is a conflict, the strategy selection overrides any other preset values.
