ht://Dig requires a configuration file and several HTML files
|
||
|
|
to operate correctly. Fortunately, when ht://Dig is
|
||
|
|
installed, a very reasonable configuration is created and in
|
||
|
|
most cases only minor modifications to the files are
|
||
|
|
necessary.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Below, we will use the variables that were set in CONFIG to
|
||
|
|
designate specific paths.

This is the main runtime configuration file for all programs

that make up ht://Dig. The file is fully described in the

When ht://Dig is installed, several attributes will be
|
||
|
|
customized to your particular environment, but for reference,
|

|

here is a sample copy of what it can look like:

# Example config file for ht://Dig.
|
||
|
|
#
|
||
|
|
# This configuration file is used by all the programs that make up ht://Dig.
|
||
|
|
# Please refer to the attribute reference manual for more details on what
|
||
|
|
# can be put into this file. (http://www.htdig.org/confindex.html)
|
||
|
|
# Note that most attributes have very reasonable default values so you
|
||
|
|
# really only have to add attributes here if you want to change the defaults.
|
||
|
|
#
|
||
|
|
# What follows are some of the common attributes you might want to change.
|
||
|
|
#
|
||
|
|
|
||
|
|
#
|
||
|
|
# Specify where the database files need to go. Make sure that there is
|
||
|
|
# plenty of free disk space available for the databases. They can get
|
||
|
|
# pretty big.
|
||
|
|
#
|
||
|
|
database_dir: /opt/www/htdig/db
|
||
|
|
|
||
|
|
#
|
||
|
|
# This specifies the URL where the robot (htdig) will start. You can specify
|
||
|
|
# multiple URLs here. Just separate them by some whitespace.
|
||
|
|
# The example here will cause the ht://Dig homepage and related pages to be
|
||
|
|
# indexed.
|
||
|
|
# You could also index all the URLs in a file like so:
|
||
|
|
# start_url: `${common_dir}/start.url`
|
||
|
|
#
|
||
|
|
start_url: http://www.htdig.org/
|
||
|
|
|
||
|
|
#
|
||
|
|
# This attribute limits the scope of the indexing process. The default is to
|
||
|
|
# set it to the same as the start_url above. This way only pages that are on
|
||
|
|
# the sites specified in the start_url attribute will be indexed and it will
|
||
|
|
# reject any URLs that go outside of those sites.
|
||
|
|
#
|
||
|
|
# Keep in mind that the value for this attribute is just a list of string
|
||
|
|
# patterns. As long as URLs contain at least one of the patterns it will be
|
||
|
|
# seen as part of the scope of the index.
|
||
|
|
#
|
||
|
|
limit_urls_to: ${start_url}
|
||
|
|
|
||
|
|
#
|
||
|
|
# If there are particular pages that you definitely do NOT want to index, you
|
||
|
|
# can use the exclude_urls attribute. The value is a list of string patterns.
|
||
|
|
# If a URL matches any of the patterns, it will NOT be indexed. This is
|
||
|
|
# useful to exclude things like virtual web trees or database accesses. By
|
||
|
|
# default, all CGI URLs will be excluded. (Note that the /cgi-bin/ convention
|
||
|
|
# may not work on your web server. Check the path prefix used on your web
|
||
|
|
# server.)

|

|
|

|
|
#
|
||
|
|
# Since ht://Dig does not (and cannot) parse every document type, this
|
||
|
|
# attribute is a list of strings (extensions) that will be ignored during
|
||
|
|
# indexing. These are *only* checked at the end of a URL, whereas
|
||
|
|
# exclude_url patterns are matched anywhere.
|
||
|
|
#
|
||
|
|
# Also keep in mind that while other attributes allow regex, these must be
|
||
|
|
# actual strings.

|
# The excerpts that are displayed in long results rely on stored information
|
||
|
|
# in the index databases. The compiled default only stores 512 characters of
|
||
|
|
# text from each document (this excludes any HTML markup...) If you plan on
|
||
|
|
# using the excerpts you probably want to make this larger. The only concern
|
||
|
|
# here is that more disk space is going to be needed to store the additional
|
||
|
|
# information. Since disk space is cheap (! :-)) you might want to set this
|
||
|
|
# to a value so that a large percentage of the documents that you are going
|
||
|
|
# to be indexing are stored completely in the database. At SDSU we found
|
||
|
|
# that by setting this value to about 50k the index would get 97% of all
|
||
|
|
# documents completely and only 3% was cut off at 50k. You probably want to
|
||
|
|
# experiment with this value.
|
||
|
|
# Note that if you want to set this value low, you probably want to set the
|
||
|
|
# excerpt_show_top attribute to false so that the top excerpt_length characters
|
||
|
|
# of the document are always shown.

# To limit network connections, ht://Dig will only pull up to a certain limit
|
||
|
|
# of bytes. This prevents the indexing from dying because the server keeps
|
||
|
|
# sending information. However, several FAQs happen because people have files
|
||
|
|
# bigger than the default limit of 100KB. This sets the default a bit higher.

# Most people expect some sort of excerpt in results. By default, if the

|

# the text defined in the no_excerpt_text attribute:
|
||
|
|
# (None of the search words were found in the top of this document.)

# Depending on your needs, you might want to enable some of the fuzzy search

# algorithms. There are several to choose from and you can use them in any

|
# combination you feel comfortable with. Each algorithm will get a weight
|
||
|
|
# assigned to it so that in combinations of algorithms, certain algorithms get
|
||
|
|
# preference over others. Note that the weights only affect the ranking of
|
||
|
|
# the results, not the actual searching.
|
||
|
|
# The available algorithms are:
|
||
|
|
# accents
|

# exact
|

# Note that if you are going to use the endings, metaphone, soundex, accents,

This file may be used in place of the header.html and footer.html
|
||
|
|
files above. It is simply the concatenation of these two files,
|
||
|
|
with the pseudo-variable <strong>$(HTSEARCH_RESULTS)</strong> as
|
||
|
|
a separator for the header and footer sections.
|
||
|
|
All the same header.html and footer.html rules apply to this file.
|
||
|
|
To make this file override the header and footer files above, you
|
||
|
|
must define the <a href="attrs.html#search_results_wrapper">
|
||
|
|
search_results_wrapper</a> attribute.

If a search produces no matches, this file is displayed. All

the relevant variables will be replaced as in the header.html

and footer.html files. The default nomatch.html is little more
|

than header.html and footer.html appended:
