        created with InMemory::open() can be passed here, which represents a
        completely empty database.

        Parameters:
        -----------

        database:  Specification of the database or databases to use.

        errorhandler_:  A pointer to the error handler to use. Ownership of
        the object pointed to is not assumed by the Xapian::Enquire object -
        the user should delete the Xapian::ErrorHandler object after the
        Xapian::Enquire object is deleted. To use no error handler, this

        The entry returned will be the best entry with that particular value

        eliminate duplicates at index time, but this may not be always be
        possible - for example the search may be over more than one Xapian
        database).

        Another use is to group matches in a particular category (e.g. you
        might collapse a mailing list search on the Subject: so that there's
        only one result per discussion thread). In this case you can use
        get_collapse_count() to give the user some idea how many other results
        there are. And if you index the Subject: as a boolean term as well as
        putting it in a value, you can offer a link to a non-collapsed search
        restricted to that thread using a boolean filter.

        This order only has an effect on documents which would otherwise have
        equal rank. For a weighted probabilistic match with no sort value,
        this means documents with equal weight. For a boolean match, with no

        percent_cutoff:  Minimum percentage score for returned documents. If a

        weight_cutoff:  Minimum weight for a document to be returned. If a
        document has a lower score that this, it will not appear in the MSet.
        It is usually only possible to choose an appropriate weight for cutoff
        based on the results of a previous run of the same query; this is thus

        Flush to disk any modifications made to the database.

        void Xapian::WritableDatabase::flush()

        For efficiency reasons, when performing multiple updates to a database
        it is best (indeed, almost essential) to make as many modifications as
        memory will permit in a single pass through the database. To ensure
        this, Xapian batches up modifications.

        Flush may be called at any time to ensure that the modifications which
        have been made are written to disk: if the flush succeeds, all the
        preceding modifications will have been written to disk.

        If any of the modifications fail, an exception will be thrown and the
        database will be left in a state in which each separate addition,
        replacement or deletion operation has either been fully performed or
        not performed at all: it is then up to the application to work out
        which operations need to be repeated.

        It's not valid to call flush within a transaction.

        Beware of calling flush too frequently: this will have a severe
        performance cost.

        Note that flush need not be called explicitly: it will be called
        automatically when the database is closed, or when a sufficient number
        of modifications have been made.

        Parameters:
        -----------

        Xapian::DatabaseError:  will be thrown if a problem occurs while
        modifying the database.

    def begin_transaction(*args):
        """
        Begin a transaction.

        void Xapian::WritableDatabase::begin_transaction(bool flushed=true)

        In Xapian a transaction is a group of modifications to the database
        which are linked such that either all will be applied simultaneously
        or none will be applied at all. Even in the case of a power failure,
        this characteristic should be preserved (as long as the filesystem
        isn't corrupted, etc).

        A transaction is started with begin_transaction() and can either be
        committed by calling commit_transaction() or aborted by calling
        cancel_transaction().

        By default, a transaction implicitly calls flush before and after so
        that the modifications stand and fall without affecting modifications
        before or after.

        The downside of this flushing is that small transactions cause
        modifications to be frequently flushed which can harm indexing
        performance in the same way that explicitly calling flush frequently
        can.

        If you're applying atomic groups of changes and only wish to ensure
        that each group is either applied or not applied, then you can prevent
        the automatic flush before and after the transaction by starting the
        transaction with begin_transaction(false). However, if
        cancel_transaction is called (or if commit_transaction isn't called
        before the WritableDatabase object is destroyed) then any changes
        which were pending before the transaction began will also be
        discarded.

        Transactions aren't currently supported by the InMemory backend.

        -----------

        newly allocated document ID. Automatically allocated document IDs come

        This method sets the metadata value associated with a given key. If

        User-specified metadata allows you to store arbitrary information in
        the form of (key,tag) pairs.

        There's no hard limit on the number of metadata items, or the size of
        the metadata values. Metadata keys have a limited length, which
        depends on the backend. We recommend limiting them to 200 bytes. Empty
        keys are not valid, and specifying one will cause an exception.

        Metadata modifications are committed to disk in the same way as
        modifications to the documents in the database are: i.e.,
        modifications are atomic, and won't be committed to disk immediately
        (see flush() for more details). This allows metadata to be used to
        link databases with versioned external resources by storing the
        appropriate version number in a metadata item.

        You can also use the metadata to store arbitrary extra information
        associated with terms, documents, or postings by encoding the termname
        and/or document id into the metadata key.

        If multiple boolean filters are specified in a query for the same

        Multiple fields can be mapped to the same prefix (so for example you
        can make site: and domain: aliases for each other). Instances of
        fields with different aliases but the same prefix will still be
        combined with the OR operator.

        For example, if "site" and "domain" map to "H", but author maps
