Subject: [lucy-user] How to add more languages in an analyzer and change path
 to store
 indexed documents

--f46d0418268eaf1c4a04c25f9b5a

Hello,

I am a beginner to Lucy. This is the first time I am using a Search
library. I went through the tutorial at lucy.apache.org. I am confused over
the following things mentioned in the tutorial.

The tutorial mentions that we can specify the language in which the
documents are. Hence while indexing how can I specify multiple languages in
the analyzers if my documents are in different languages.

my $polyanalyzer = Lucy::Analysis::PolyAnalyzer->new(
       language => 'en',
       )

How can I specify multiple languages such as Danish, German, Finnish etc
etc.

Secondly the path_to_index given in the tutorial is '/store/lucy_test'.
This path was given in the sample tutorial when I downloaded the
apache-lucy-0.3.1 library. Now if I want to change this path meaning I want
to store my indexed documents at a different location how can I do that?
The location /store/lucy_test contains different sub-folder viz. locks,
schema_26.json, set_26, snapshot_26.json

The code in indexer.pl is

my $path_to_index = '/store/lucy_test';

use Lucy::Index::Indexer;

my $indexer = Lucy::Index::Indexer->new(
      index => $path_to_index,
      schema => $schema,
      create => 1,
      truncate => 1,
);

Also what do the 'create'  and 'truncate' parameters specify in this case?

I changed the default path in the tutorial '/store/lucy_test' to
'/store_test'. The script indexer.pl ran perfectly. Then in the
cgi-search.pl I made the same change to the $path_to_index variable. It
gave the following error -

*Index doesn't seem to contain any data*
* lucy_IxReader_do_open at
/root/apache-lucy-0.3.1/perl/../core/Lucy/Index/IndexReader.c*
*
*
After I made the change to the $path_to_index variable in indexer.pl and
ran the script the following folders were created in the path - locks and
seg_1.

I am terribly stuck and I am not able to go forward. Please bear with the
question. Thank you for you patience.

Thank you.
