add direction penalties
...
Direction penalties are estimated by getting the name to address
ratio usage for each partial term in the query and computing the
linear regression of that ratio over the entire phrase. Or to put
it in ither words: we try to determine if the terms at the beginning
or the end of the query are more likely to constitute a name.
Direction penalties are currently used only in classic name queries.

search: merge QueryPart array with QueryNodes
...
The basic information on terms is pretty much always used together
with the node inforamtion. Merging them together saves some
allocation while making lookup easier at the same time.
