Description
The first two optional parameters specify comparison
and susbstitution types. The default type is
Prefix and Case
(case insensitive prefix match).
Alias in indexer.conf
Alias can be used to organize search through
a master site by indexing
its mirror.
It is also useful to index your own site directly from
the local file system, to avoid invoking HTTP
server into indexing process and thus offload the server.
Note:
Direct indexing from the local file system works mostly
in case of a static site. If your site has many dynamic
documents, such as CGI scripts or PHP programs,
indexing from the file system may not work as expected.
If an Alias command is specified
for some site only in indexer.conf,
URL substitution is done by indexer just
before
downloading a document, while search.cgi
will display document addresses in the
master site URL
notation in search results.
Alias in search.htm
If an Alias command is specified
only in search.htm, URL substitution is done by
search.cgi when displaying search results,
so the user will see addresses
in the mirror
site URL notation, while indexer
will download the documents from
the master site at indexing time.
