Xapian is a highly adaptable toolkit which allows developers to easily
add advanced indexing and search facilities to their own applications.
It has built-in support for several families of weighting models
and also supports a rich set of boolean query operators.
In addition to the doc strings provided by this python library, you
may wish to look at the library's overall documentation, either
installed along with the bindings or online at
<https://xapian.org/docs/bindings/python/>, as well as the library's
documentation, possibly installed with the library or with its
development files, or again online at <https://xapian.org/docs/>.

A handle representing a document in a Xapian database.
The Document class fetches information from the database lazily.
Usually this behaviour isn't visible to users (except for the speed
benefits), but if the document in the database is modified or deleted,
then preexisting Document objects may return the old or new versions
of data (or throw Xapian::DocNotFoundError in the case of deletion).
Since Database objects work on a snapshot of the database's state, the
situation above can only happen with a WritableDatabase object, or if
you call Database::reopen() on a Database object.
We recommend you avoid designs where this behaviour is an issue, but
if you need a way to make a non-lazy version of a Document object, you
can do this like so:doc =

The string supplied in str_ is used by operator() to decide whether

Xapian::NumberValueRangeProcessor::NumberValueRangeProcessor(Xapian::valueno
slot_, const std::string &str_, bool prefix_=true)
Xapian::NumberValueRangeProcessor::NumberValueRangeProcessor
Parameters:
-----------
slot_: The value number to return from operator().
str_: A string to look for to recognise values as belonging to this
numeric range.
prefix_: Whether to look for the string at the start or end of the
values. If true, the string is a prefix; if false, the string is a
suffix (default: true).
The string supplied in str_ is used by operator() to decide whether
the pair of strings supplied to it constitute a valid range. If
prefix_ is true, the first value in a range must begin with str_ (and
the second value may optionally begin with str_); if prefix_ is false,
the second value in a range must end with str_ (and the first value
may optionally end with str_).
If str_ is empty, the setting of prefix_ is irrelevant, and no special
strings are required at the start or end of the strings defining the
range.
The remainder of both strings defining the endpoints must be valid
floating point numbers. (FIXME: define format recognised).
For example, if str_ is "$" and prefix_ is true, and the range
processor has been added to the queryparser, the queryparser will
accept "$10..50" or "$10..$50", but not "10..50" or "10..$50"
as valid ranges. If str_ is "kg" and prefix_ is false, the
queryparser will accept "10..50kg" or "10kg..50kg", but not
"10..50" or "10kg..50" as valid ranges.
