[EP-tech] Re: [SOLVED] Re: How to set a field to be multilang (search)

Sorry Adam,
My bad. In my anxiety to make it work, I forgot that the search only deals with archive dataset. Once I moved my imported files to be public, everything worked OK. 

Sorry for the false alarm!

PS. By manually reindexing I meant using epadmin reindex

Our set_value function is calling eprint->set_value on the ml_title field -- that should trigger indexing.  What do you mean by 'manually reindex'?

Adam,

There's one more problem, which reopens this thread. When I imported a
BibTeX entry, I waited for more than a minute and I wasn't able to find
the new entry using the search operation. When I manually reindexed my
dataset it worked. Is this normal epindexer behaviour (I mean is
epindexer not triggered after using imports) or is it related to our
VirtualField's set_value function?

Thanks all in advance and have a nice weekend, everybody!

Hi Adam,

Instead of adding it to the wiki, shouldn't the package maintainer be
notified accordingly in order to add it as a dependency? And if so, how
do we do this?

Thanks again!

Well, my training course page is coming together (I've been working on it today), and it has a section on troubleshooting searching already.  Perhaps you could add some notes to the page with the video on it.

Ooops...indexer!?!??! :):)

Never heard of it!!!:)

OK, I corrected it. I tried to see what was happening in my system, and
my epindexer installation was missing a dependency:

So now, after making a change in one of my eprint's title, after a
minute or so, the search worked as expected!

But the problem is that this information was (and still is) missing from
the wiki wrt to EPrints installation in Debian. The package
libconfig-general-perl should be added in the dependencies section!

Thanks again!

Hi George

	It doesn't look like you've done anything wrong.  For it to show up in the searches, the field has to have been indexed.  What do you mean by 'manually reindex'?  Is your indexer running well?  Is it indexing the ml fields?

Hi all,

As promised, I'm back with the search within multilang fields:). My
problem is that it seems that I cannot search correctly within my
multilingual title and abstract fields (ml_title and ml_abstract
respectively), unless my dataset is reindexed manually.

What I've done so far is the following: I've added a script for each
type of search (advanced and simple) that basically replaces the
original fields with their multilingual counterparts. So I've added
archives/myrepo/cfg/cfg.d/eprint_search_advanced_local.pl:

$c->{search}->{advanced} =
{
    search_fields => [
        { meta_fields => [ "documents" ] },
        { meta_fields => [ "ml_title" ] },
        { meta_fields => [ "creators_name" ] },
        { meta_fields => [ "ml_abstract" ] },
        { meta_fields => [ "date" ] },
        { meta_fields => [ "collection" ] },
        { meta_fields => [ "keywords" ] },
        { meta_fields => [ "subjects" ] },
        { meta_fields => [ "type" ] },
        { meta_fields => [ "department" ] },
        { meta_fields => [ "editors_name" ] },
        { meta_fields => [ "ispublished" ] },
        { meta_fields => [ "refereed" ] },
        { meta_fields => [ "publication" ] },
        { meta_fields => [ "documents.format" ] },
    ],
    preamble_phrase => "cgi/advsearch:preamble",
    title_phrase => "cgi/advsearch:adv_search",
    citation => "result",
    page_size => 20,
    order_methods => {
        "byyear"     => "-date/creators_name/title",
        "byyearoldest"   => "date/creators_name/title",
        "byname"     => "creators_name/-date/title",
        "bytitle"    => "title/creators_name/-date"
    },
    default_order => "byyear",
    show_zero_results => 1,
};

and archives/testpamak1/cfg/cfg.d/eprint_search_simple_local.pl:

$c->{search}->{simple} =
{
    search_fields => [
        {
            id => "q",
            meta_fields => [
                "documents",
                "ml_title",
                "ml_abstract",
                "creators_name",
                "date"
            ]
        },
    ],
#   preamble_phrase => "cgi/search:preamble",
    title_phrase => "cgi/search:simple_search",
    citation => "result",
    page_size => 20,
    order_methods => {
        "byyear"     => "-date/creators_name/title",
        "byyearoldest"   => "date/creators_name/title",
        "byname"     => "creators_name/-date/title",
        "bytitle"    => "title/creators_name/-date"
    },
    default_order => "byyear",
    show_zero_results => 1,
};


When I search for a keyword which exists in one of my deposits' ml_title
field, both search functions return nothing, unless I manually reindex
my dataset. After that, searches work as expected.

What exactly am I doing wrong and needs to be taken care of?

Thanks all in advance!

George.
