DESCRIPTION

This trait extends an existing document corpus by search functionality. In that it leverages Plucene. It follows the abstract trait outlined in TM::Corpus::SearchAble, so the documentation there applies.

INTERFACE

directory

Getter/setter method for the file location of the index. In this case this will be a directory (which will be created if it does not exist).

index

$co->index;

This method creates/updates the index.

search

@results = @{ $co->search ($phrase) }

This method takes a search phrase as input and delivers a list (reference) of results.

The search phrase will by default search in the content of the documents in the corpus.

Example:

   $co->search ('something');    # will search in content

   $co->search ('content:"something"'); # same
