DWDS/Dialing Concordance Code

v2.0.38-pre4: count() refactoring, keys() queries, bugfixes
+ re-factored count-query evaluation from ConcHolder.(h|cpp) into QCount.(h|cpp)
- removed some redundant CQueryResult fields from CConcHolder (m_SortOrder, m_bSortByString)
+ re-factored CConcHolder::GetHits(): added variant for pre-parsed queries
+ removed implicit space-separation in CQCountKeyExprList; we already have globalCountKeyDelim=\002, which is ugly but more useful
+ fixed bug setting Result.m_AllHitsCount in ConvertCountsToHits()
- we were getting m_AllHitsCount=512 (== Limit == m_pIndexator->m_MaxCachedHitsCount) for subcorpora with more real count-hits
+ added keys() query type: extract tuples to query from a count()-query
- pretty ugly: it needs to evaluate the count()-query in CQKeys::Compile() in order to generate a proxy query
(in general CQWith-conjunction of CQTokSet queries)
- currently over-generates, since the key attributes are queried independently

+ added query doc notes for Compile(), Evaluate()

+ updated query docs for count sort limits

v2.0.38-pre3:
+ added optional lower- and upper-bound arguments to count()-query sort operators #(ASC|DESC)_BY_(KEY|COUNT)
- caveat numerator: these apply on a per-subcorpus basis; could be problematic for sparse counts across many subcorpora

+ updated to v2.0.38-pre3

+ re-added indexName tracking to CQTokAny (helpful for DiaCollo parsing, doesn't hurt ddc)

+ updated docs

+ fixes for perl wrappers: use CQCountKeyExprList* m_keys in CQCount (vs. old ref), for better perl-wrappability

+ v2.0.38 tweaks for perl wrappers

+ updated docs
