<h2><a name="i">NMZ.i</a></h2>
<p>Index file for word searching. (inverted file)</p>
<h3>Structure</h3>
For each word, the pair of [documentID containing that word][score]
is stored sequencially, making the record for the word.
The record is of variable length, the byte count of each data part
is placed in front of them.
<pre>
[data length for word1][documentID][score][documentID][score]...
[data length for word2][documentID][score][documentID][score]...
[data length for word3][documentID][score][documentID][score]...
:
</pre>
<h3>Note</h3>
<ul>
<li>DocumentID are sorted in ascending order --INPORTANT.
<li>DocumentID are stored by only gaps.<br>
e.g., 1, 5, 29, 34 -> 1, 4, 24, 5
<li>Data is stored in "pack 'w'" format. (BER compression)
</ul>
<h2><a name="ii">NMZ.ii</a></h2>
<p>Index for 'seek'ing NMZ.i.</p>
<h3>Structure</h3>
<pre>
[position of word 1 in NMZ.i][position of word 2 in NMZ.i]
[position of word 3 in NMZ.i]...
</pre>
<h3>Note</h3>
<ul>
<li>All data is in binary. (pack 'N')
</ul>
<h2><a name="w">NMZ.w</a></h2>
<p>
List of words.
</p>
<h3>Structure</h3>
<p>
A simple line-oriented text. Sorted in ascending order. You can seek
NMZ.ii by line number. (Note: line number = wordID)
</p>
<h3>Note</h3>
<ul>
<li>Words are sorted in ascending order. (list of words are recorded in "NMZ.w")
<li>Regular Expression/substring/suffix matching greps the entire file.
<li>Characters in JIS X 0208 are recored in EUC-JP.
</ul>

<p>Index for 'seek'ing NMZ.w </p>

<h3>Note</h3>
<ul>
<li>All data is in binary. (pack 'N')
</ul>
<h2><a name="r">NMZ.r</a></h2>
<p>List of files registered in index.</p>
<h3>Structure</h3>
<p>
Each line records a document file which is registered in the index
file. However, a line beginning with '#' indicates a file deleted
from the index. A line beginning with '##' indicates comment.
Example:
</p>
<pre>
/home/foo/bar1.html
/home/foo/bar2.html
/home/foo/bar3.html
## indexed: Sun, 08 Jan 2006 02:28:00 +0900
(an empty line)
# /home/foo/bar1.html
## deleted: Sun, 08 Jan 1998 12:34:56 +0900
</pre>
<h2><a name="p">NMZ.p</a></h2>
<p>Index for phrase searching.</p>
<h3>Description</h3>
<p>
Two words are converted to a 16 bit hash value. For phrase
searching, all words in a phrase are 'AND'ed and searched,
then check the word order by referring NMZ.p. Note that the
word order are recorded for each two word pairs. So, to
search "foo bar baz", documents including "foo bar" or "bar
baz" are retrieved. By collision of hash values,
inappropriate documents may also be retrieved. Though phrase
search is inaccurate, it usually works fine.
</p>
<h3>Structure</h3>
<pre>
|<------ data byte count (1) ------->|
[data byte count(1)][documentID including hash value \x0000]...
|<------ data byte count (2) ------->|
[data byte count(2)][documentID including hash value \x0001]...
...
[data byte count(n)][documentID including hash value \xffff]...
</pre>
<h3>Note</h3>
<ul>
<li>DocumentID are sorted in ascending order. -- IMPORTANT
<li>DocumentID are stored by only gaps.<br>
e.g., 1, 5, 29, 34 -> 1, 4, 24, 5
<li>All data is stored in "pack 'w'". (BER compression)
</ul>
<h2><a name="pi">NMZ.pi</a></h2>
<p>Index of index for phrase searching.</p>

</pre>
<h3>Note</h3>
<ul>
<li>All data is in binary. (pack 'N')
<li>Always 256 Kb
</ul>
<h2><a name="t">NMZ.t</a></h2>
<p>Record information about time stamps and deleted documents.</p>
<h3>Description</h3>
<p>
File time stamps are recorded in 32 bits. This is used for sorting
search results by date. Also, if value is -1, then the document is
regarded as deleted.
</p>
<h3>Structure</h3>
<pre>

<ul>
<li>All data is in binary. (pack 'N')

</ul>
<h2><a name="field">NMZ.field.{subject,from,date,message-id,...}</a></h2>
<p>File to record field information.</p>
<h3>Description</h3>
<p>
Used in field-specified searching. A simple line-oriented
text. grep'ed by the regular expression engine. A line
number can be used as a documentID. Also, used in displaying
the search results.
</p>
<h3>Structure</h3>
<p>
A simple line-oriented text. (line number = documentID)
</p>
<h3>Note</h3>
<p>
Since it is a line-oriented text, it can be edited by an
editor or other tools. In case you edit, you should rebuild
<a
href="#field-i">NMZ.field.{subject,from,date,message-id,...}.i</a>
files by <a href="manual.html#rfnmz">rfnmz</a>.
</p>
<h2><a name="field-i">NMZ.field.{subject,from,date,message-id,...}.i</a></h2>

<h3>Note</h3>

<li>All data is in binary.
<li>All data is in binary. (pack 'N')

<h2><a name="access">NMZ.access</a></h2>
<p>Configuration file for user access control.</p>
<h3>Structure</h3>
<p>
Access control by IP address, host name and/or domain name.
<code>deny</code> defines hosts from which you deny user
access, and <code>allow</code> defines hosts from which you
allow user access. When host is specified by IP address,
prefix matching is used, and when host if specified by host
name or domain name, suffix matching is
used. <code>all</code> indicates all hosts. Configuration is
evaluated from the top. Example:
</p>
<pre>
deny all
allow localhost
allow 123.123.123.
allow .example.jp
</pre>
<p>
This configuration allows access from the localhost, hosts
with IP address 123.123.123.*, or hosts with domain name
*.example.jp. Access from other hosts are denied.
</p>
<p>
For Apache web sever, access control by host name and/or
domain name requires the following description in
"httpd.conf".
</p>
<pre>
HostnameLookups On
</pre>
<h2><a name="status">NMZ.status</a></h2>
<p>Data necessary to update index is stored.</p>

<h3>Description</h3>
<p>

${title} is replaced by the contents of
NMZ.field.title. ${namazu::counter} and ${namazu::score} have special
meanings. They are replaced by the counter of search results and its
score respectively.
</p>
<p>
By default, NMZ.result.normal and NMZ.result.short are provided.
Users can freely create NMZ.result.*.
