- Update to 1.4.14:
* API:
+ Xapian::QueryParser: Handle "" inside a quoted phrase better. In a quoted
boolean term, "" is treated as an escaped ", so handle it in a compatible way
for quoted phrases. Previously we'd drop out of the phrase and start a new
phrase. Fixes#630, reported by Austin Clements.
+ Xapian::Stem: The constructor which takes a stemmer name now takes an
optional second bool parameter - if this is true, then an unknown stemmer
name falls back to using the "none" stemmer instead of throwing an exception.
This allows simply constructing a stemmer from an ISO language code without
having to worry about whether there's a stemmer for that language, and
without having to handle an exception if there isn't.
+ Xapian::Stem: Fix a bug with handling 4-byte UTF-8 sequences which
potentially affects most of the stemmers. None of the stemmers work in
languages where 4-byte UTF-8 sequences are part of the alphabet, but this
bug could result in invalid UTF-8 sequences in terms generated from text
containing high Unicode codepoints such as emoji, which can cause issues (for
example, in some language bindings). Fix synced from Snowball git post
2.0.0.
+ Xapian::Stem: Add a new is_none() method which tests if this is a "none"
stemmer.
+ Xapian::Weight: The total length of all documents is now made available to
Xapian::Weight subclasses, and this is now used by DLHWeight, DPHWeight and
LMWeight. To maintain ABI compatibility, internally this still fetches the
average length and the number of documents, multiplies them, then rounds the
result, but in the next release series this will be handled directly.
+ Xapian::Database::locked() on an inmemory database used to always return
false, but an inmemory Database is always actually a WritableDatabase
underneath, so now we always report true in this case because it's really
always report being locked for writing.
