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

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: 

# systemctl status epindexer.service
epindexer.service - SYSV: Start the eprints indexer daemon as the correct user 
   Loaded: loaded (/etc/init.d/epindexer)
Active: failed (Result: exit-code) since Wed 2015-10-07 16:42:25 EEST; 13s ago Process: 6517 ExecStart=/etc/init.d/epindexer start (code=exited, status=2)

Oct 07 16:42:25 pamak-e-prints systemd[1]: Unit epindexer.service entered failed state. 
Hint: Some lines were ellipsized, use -l to show in full.

I installed the missing library and started epindexer:

# apt-get install libconfig-general-perl
# service epindexer start
# service epindexer status

   Loaded: loaded (/etc/init.d/epindexer)

Oct 07 16:50:43 pamak-e-prints epindexer[7841]: Starting EPrints Indexer: [ OK ]
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.
