| Summary : filter documents for indexing with Swish-e
|
Description :
SWISH::Filter provides a unified way to convert documents into a type that
Swish-e can index. Individual filters are installed as separate subclasses
(modules). For example, there might be a filter that converts from PDF
format to HTML format.
SWISH::Filter is a framework that relies on other packages to do the heavy
lifting of converting non-text documents to text. *Additional helper
programs or Perl modules may need to be installed to use SWISH::Filter to
filter documents.* For example, to filter PDF documents you must install
the \'Xpdf\' package.
The filters are automatically loaded when \'SWISH::Filters->new()\' is
called. Filters define a type and priority that determines the processing
order of the filter. Filters are processed in this sort order until a
filter accepts the document for filtering. The filter uses the document\'s
content type to determine if the filter should handle the current document.
The content-type is determined by the files suffix if not supplied by the
calling program.
The individual filters are not designed to be used as separate modules. All
access to the filters is through this SWISH::Filter module.
Normally, once a document is filtered processing stops. Filters can filter
the document and then set a flag saying that filtering should continue (for
example a filter that uncompresses a MS Word document before passing on to
the filter that converts from MS Word to text). All this should be
transparent to the end user. So, filters can be pipe-lined.
The idea of SWISH::Filter is that new filters can be created, and then
downloaded and installed to provide new filtering capabilities. For
example, if you needed to index MS Excel documents you might be able to
download a filter from the Swish-e site and magically next time you run
indexing MS Excel docs would be indexed.
The SWISH::Filter setup can be used with -S prog or -S http. It works best
with the -S prog method because the filter modules only need to be loaded
and compiled one time. The -S prog program _spider.pl_ will automatically
use SWISH::Filter when spidering with default settings (using \"default\" as
the first parameter to spider.pl).
The -S http indexing method uses a Perl helper script called _swishspider_.
_swishspider_ has been updated to work with SWISH::Filter, but (unlike
spider.pl) does not contain a \"use lib\" line to point to the location of
SWISH::Filter. This means that by default _swishspider_ will *not* use
SWISH::Filter for filtering. The reason for this is because _swishspider_
runs for every URL fetched, and loading the Filters for each document can
be slow. The recommended way of spidering is using -S prog with spider.pl,
but if -S http is desired the way to enable SWISH::Filter is to set
PERL5LIB before running swish so that _swishspider_ will be able to locate
the SWISH::Filter module. Here\'s one way to set the PERL5LIB with the bash
shell:
$ export PERL5LIB=`swish-filter-test -path`
