[Xapian-discuss] Xapian 1.0.21 released

[Olly Betts]

I've uploaded Xapian 1.0.21 (including Search::Xapian 1.0.21.0), which
as usual you can download from:

http://xapian.org/download

The most notable changes in this release are:

Xapian-core API:

* Xapian::Stem now recognises "nb" and "nn" as additional codes for the
  Norwegian stemmer.

* Xapian::QueryParser now correctly parses a wildcarded term in between two
  other terms (ticket#484).

Matcher:

* OP_OR could skip a matching document if it decayed to OP_AND or OP_AND_MAYBE
  during the match in some cases.  Fixes ticket#476.

* OP_XOR with non-leaf subqueries could skip matching documents in some cases,
  and OP_XOR of three or more sub-queries could return incorrect weights.
  Fixes ticket#475.

* OP_OR is now more efficient if a subquery is potentially expensive (e.g.
  OP_VALUE_RANGE, OP_NEAR, OP_PHRASE, PostingSource).  A 10-fold speed-up with
  OP_VALUE_RANGE has been observed.

Build System:

* Install files to make Xapian easier to use with cmake.

Portability

* On x86 processors, Xapian now defaults to using SSE2 FP instructions.  This
  avoids issues with excess precision and it a bit faster too.  If you need to
  support processors without SSE2 (this means pre-Pentium4 for Intel) then
  configure with --disable-sse.  (ticket#387)
