Wais 2.311

Wais is a Perl module with access to freeWAIS-sf libraries.

USAGE

The main high-level interface are the functions Wais::Search and Wais::Retrieve. Both return a reference to an object of the class Wais::Result.

Wais::Search

Arguments of Wais::Search are hash references, one for each database to search. The keys of the hashes should be:

query

The query to submit.

database

The database which should be searched.

host

host is optional. It defaults to localhost.

port

port is optional. It defaults to 210.

tag

A tag by which individual results can be associated to a database/host/port triple. If omitted defaults to the database name.

relevant

If present must be a reference to an array containing alternating document ids and types. Document ids must be of type Wais:Docid.

Here is a complete example:

$result = Wais::Search({query => pfeifer,
database => $db1,
host => ls6,
relevant => [$id, TEXT]},
{query => pfeifer,
database => $db2});

If host is localhost and database.src exists, local search is performed instead of connecting a server.

Wais::Search will open $Wais::maxnumfd connections in parallel at most.
