[EP-tech] Re: Relevance ranking for Simple and Advanced Search



Dear Brian,

Thank you for this information!  I was having trouble getting the advanced search to use relevance sort, and your post solved it for me.
I think that relevance sort is what users expect as a default sort.
Should we update the simple and advanced search config examples here: http://wiki.eprints.org/w/Search.pl to use relevance sort by default?

Tomasz

Subject: [EP-tech] Relevance ranking for Simple and Advanced Search

All,

Just passing this along in case anyone has been looking at searching (simple and advanced) and wondering about how to make relevance ranking results the default for at least the 3.3.12 (version we are running) of Eprints.  As usual... your millage may vary.

In our Eprints 3.3.12 instance we changed the following files and ran 'epadmin reload {archive}' to make the changes stick.

cfg/cfg.d/eprints_search_simple.pl:

        preamble_phrase => "cgi/search:preamble",
        title_phrase => "cgi/search:simple_search",
        citation => "result",
        page_size => 20,
        order_methods => {
                "byrelevance"    => "",
                "byyear"         => "-date/creators_name/title",
                "byyearoldest"   => "date/creators_name/title",
                "byname"         => "creators_name/-date/title",
                "bytitle"        => "title/creators_name/-date"
        },
        #default_order => "byyear",
        default_order => "byrelevance",
        show_zero_results => 1,

cfg/cfg.d/eprints_search_advanced.pl:

        preamble_phrase => "cgi/advsearch:preamble",
        title_phrase => "cgi/advsearch:adv_search",
        citation => "result",
        page_size => 20,
        order_methods => {
                "byrelevance"    => "",
                "byyear"         => "-date/creators_name/title",
                "byyearoldest"   => "date/creators_name/title",
                "byname"         => "creators_name/-date/title",
                "bytitle"        => "title/creators_name/-date",
                "byid"           => "eprintid",
        },
        #default_order => "byyear",
        default_order => "byrelevance",
        show_zero_results => 1,

By adding the "byrelevance" line to the order_methods and setting the default_order to "byrelevance" we now have relevance ranking search results for both our simple and advanced searches by default.

Hope this helps,
Thanks,
Brian.
