This guide is intended for those upgrading from 3.1.x or
|
|
earlier versions to 3.2.x. The best advice is
|
|
<em>don't</em>. That is, it is highly recommended that you
|
|
install the 3.2 release in a separate directory tree and treat
|
|
everything as if you were installing it for the first
|
|
time. This is not just because this is a beta release. There
|
|
are several main reasons for this:
|
|
<ul>
|
|
<li>The htmerge program now <strong>only</strong> merges. You
|
|
do not need to run it after running htdig as before. The
|
|
"cleanup" duties have been moved to the <a
|
|
href="htpurge.html">htpurge</a> program that also deletes
|
|
URLs. The sample rundig script is modified accordingly.</li>
|
|
<li>The default directory structure of this release is
|
|
different from previous releases, more in line with other UNIX
|
|
programs.</li>
|
|
<li>The databases are all in different formats. This version
|
|
cannot read databases from previous versions since the new
|
|
formats have significantly more information and this cannot be
|
|
reconstructed from old databases. This goes for fuzzy
|
|
databases as well. Future versions can use the new <a
|
|
href="htdump.html">htdump</a> and <a
|
|
href="htload.html">htload</a> programs to dump and load
|
|
databases to/from text files. These will also allow databases
|
|
to be transfered between platforms.
|
|
</li>
|
|
</ul>
|
|
Text files, such as config files, result templates, etc. are
|
|
the same between releases, so you will probably wish to copy
|
|
these to your new installation.</li>
|
|
</p>
|
|
|
|
<p>
|
|
Additionally, you may find things a bit rough at first. We
|
|
appreciate your comments and suggestions, especially in the
|
|
form of performance comparisons with the 3.1.x
|
|
releases. Additionally, there are several things planned for
|
|
the final 3.2.0 release that have not been implemented yet:
|
|
<ul>
|
|
<li>Proximity (near) searching.</li>
|
|
<li>Phrase searching method (in addition to and, or, and boolean).</li>
|
|
<li>Field-based searching--restricting to a header, title, etc.</li>
|
|
<li>Date-based searching--restricting to a range of dates.</li>
|
|
<li>Implementation of a more accurate scoring system.</li>
|
|
<li>Parallel indexing and searching.</li>
|
|
<li>Support for https: and ftp: access</li>
|
|
</ul>
