 As Xapian has a higher 'qs' score than Internal it will (once enabled) override the default EPrints simple search. You can override this behaviour in '''cfg.d/plugins.pl''':
-<pre>  $c-&gt;{plugins}{'Search::Xapian'}{params}{qs} = .1;</pre>
+<pre>  $c-&gt;{plugins}{'Search::Xapian'}{params}{qs} = -1;</pre>

 ==USAGE==
 Install the [http://search.cpan.org/search?query=xapian&mode=dist Search::Xapian] extension. Note: there are two Perl bindings available for Xapian. The CPAN version is older and based on Perl-XS. xapian-bindings-perl available from xapian.org is based on SWIG and has better coverage of the API. Regardless, for the best feature support/performance it is highly recommended to have the latest stable version of the Xapian library.

-The indexing process for Xapian is in ''lib/cfg.d/search_xapian.pl''. This can be overridden by dropping the same-named file into your repository ''cfg.d/''. If the Xapian search is not matching what you might expect it to, you probably need to fix the indexing process (and re-index!). Terms indexed by Xapian can also be weighted to e.g. give names a higher weighting than abstract text.

 ===Lock Files===
-Xapian maintains a lock file in ''var/xapian''. If you see indexing errors about not being able to lock the database ensure you aren't running multiple copies of the EPrints {{API:PodLink|file=bin|package_name=bin|section=indexer|text=indexer}}.
