RE: [lucy-user] Doc id from hits and remove redundant documents

[Gupta, Rajiv]

Thanks for your reply Nick. 

I wanted to delete the old documents that is why I was trying to get the doc_id 
and use that to delete it. However, that does not help it deleted other 
documents and keep changing the document. I wanted to use delete by term but in 
my doc I don't have any primary key. 

I add document like this:

$indexer->add_doc({
                title    => $mytitle,
                content  => substr($mybodytext,0,1024),
                url      => $onlyfilename,
                urlpath  => $filpath,
                position => $fileseektostart,
                linenum  => $filelinenumtostart,
                jobtype  => $self->{_logfile_hash}{$filetoindex}[5] ,
            });

The title is the key that I use to query for any search. Will term be its value?

The title key values are [1,2,3,4] then will that work?

$indexer->delete_by_term(
    field => 'title'  # required
    term  => 4   # required
);

Thanks,
Rajiv

Oops, this should have been:

     $indexer->delete_by_term(
         field => 'my_primary_key',
         term  => $value,
     );
