- Update to 1.4.3: * MSet::snippet(): Favour candidate snippets which contain more of a diversity of matching terms by discounting the relevance of repeated terms using an exponential decay. A snippet which contains more terms from the query is likely to be better than one which contains the same term or terms multiple times, but a repeated term is still interesting, just less with each additional appearance. Diversity issue highlighted by Robert Stepanek's patch in https://github.com/xapian/xapian/pull/117 - testcases taken from his patch. * MSet::snippet(): New flag SNIPPET_EMPTY_WITHOUT_MATCH to get an empty snippet if there are no matches in the text passed in. Implemented by Robert Stepanek. * Round MSet::get_matches_estimated() to an appropriate number of significant figures. The algorithm used looks at the lower and upper bound and where the estimate sits between them, and then picks an appropriate number of significant figures. Thanks to Sébastien Le Callonnec for help sorting out a portability issue on OS X. * Add Database::locked() method - where possible this non-invasively checks if the database is currently open for writing, which can be useful for dashboards and other status reporting tools. * See also https://xapian.org/docs/xapian-core-1.4.3/NEWS - Update to 1.4.2: * Add XAPIAN_AT_LEAST(A,B,C) macro. * MSet::snippet(): Optimise snippet generation - it's now ~46% faster in a simple test. * Add Xapian::DOC_ASSUME_VALID flag which tells Database::get_document() that it doesn't need to check that the passed docid is valid.
