[EP-tech] Re: exact match on advanced search

Hi,
I have already seen an advice about using "id" and I had a a small concern about it.
The Wiki says (http://wiki.eprints.org/w/Category:EPrints_Metadata_Fields#Internal-use_and_Deprecated_Field_Types) : 

     Internal-use and Deprecated Field Types

        Basic metadata field
            File - virtual field represtenting the files in a document
   *  Id - deprecated (do not use)*
            Int
                Year - deprecated (do not use)

So is the Wiki right or not ? Is 'ID" really safe to use ?
We had to find a way to search on multiword keywords and so we also needed exact matches. 
As ID is advertised as "do not use", we had to find another way.
We ended up adding a "match" attribute to the field definition,...

   {
            name => 'agrovoc_mat',
            type => 'compound',
            multiple => 1,
            input_boxes => 3,
            fields => [
                    {
                            sub_name => 'motcle',
                            type => 'text',
                            sql_index => 1,
   *match => 'EX',*
                            browse_link => 'agrovoc_mat',
                    },
                    {
                            sub_name => 'id',
                            type => 'bigint',
                    },
            ],
   },

BTW, I'm not sure at all whether this solution is safer or not...

If someone can clarify that, it would be nice.

Thanks.
GF

What type of field is it? Text? Try changing to id - this doesn't do any preprocessing of search terms.

    Hi!

      I would like to change a text search on a field to be an exact
    match.

    now I've:

        search_fields => [
           { meta_fields => [ $EPrints::Utils::FULLTEXT ] },
           { meta_fields => [ "localizzazione" ] },
           { meta_fields => [ "tipo_fruizione" ] },
           { meta_fields => [ "collocazione" ] },

    [..]

    I would like to have the "localizzazione" field to be an exact match
    instead of a text search (which instead removes dots, spaces and
    so on).

    Which is the best way to do it? I need it in the advanced search
    form,
    it is not a custom script (which can use filters and works).
