I understood this but didn't understand why the high level api
returned more results for query that went basically exact match on
logical field x. I guess I'll understand that from the docs, and if
not I'll ask again :)
Usually it is the other way round, i.e. p_r_s() returns less hits than
s_p(). This is because p_r_s() filters collections while s_p() searches
regardless of collection. Hence the latter may get restricted records,
deleted records, and whatnot. Was it really the other way round,
p_r_s() giving more records than s_p() in your case? If so, we should
have closer look.
It is indeed as I described.
But as far as I understand it (here you're the experts) this stems from
the fact that search_pattern() does not really like a complex query like
"pub:2008->2012", right?
I admit I used search_pattern() mainly cause it returned an intbitset
straight away. (I've to do bean counting at the moment it is convenient
to use intersect, difference, union and friends.) However, I feel I
really want something like
intbitset(perform_request_search(p=searchstring)) instead, allowing for
the more advanced parameters of p_r_s() and the identical results
compared to the usual websearch, ie. I don't have to take care of
deleted records and such.
