[edit] Not To Be Missed
Worth Noting
- MySQL, by default, indexes words 4 characters or longer. Shorter
words are therefore not searchable. This can be changed if desired. It
requires having the following configuration directive in the [mysqld] section of the MySQL configuration file (usually /etc/my.cnf):
ft_min_word_len=2
Once this is done, existing fulltext indexes will need to be rebuilt. The following command does the job nicely in MySQL.
REPAIR TABLE tbl_name QUICK - There are other situations where you might need to repair tables or
rebuild indexes. Migration of tables from one version of MySQL to
another can be such a case. Signs of trouble may be subtle. Boolean
searching has been known to fail quietly. In addition to the REPAIR
command above, you can try...
REPAIR TABLE tbl_name USE_FRM

[edit] Easily Overlooked
- The amount of time it takes for thumbnail images to display in the browser can be reduced dramatically by creating a symlink for each collection like this....
cd $DLXSROOT/web/c/coll
ln -s $DLXSROOT/img/c/coll/index thumb
The only drawback to this approach is that it bypasses the cgi and authentication for thumbnails by essentially putting them under the web document root. If thumbnail security is important, don't create the symlink.
[edit] A Common Problem
- If you get a division by zero error from the Image Class CGI when trying to view a full size image, double check the installation of mrsid_retrieve. Most likeley, it is not installed properly.
