Did you know that Sphinx and Manticore Search configs allow you to do scripting by using shebang syntax ? Here is an example of how useful it can be in some cases:
Imagine you have 3 tables with identical structure that you would like to index into 3 indexes one per table. You can just make a php script which will do it and use it as a Manticore Search config instead of describing each source/index separately:
#!/usr/bin/php
<?php
$source= "source [TABLE]_src {
type = mysql
sql_host = localhost
sql_user = user
sql_pass = password
sql_db = db
sql_port = 3306
sql_query = SELECT [TABLE].id, title, body FROM [TABLE] WHERE [TABLE].id >=\$startand[TABLE].ID <=\$end
sql_query_range = SELECT MIN(id), MAX(id) FROM [TABLE]
sql_range_step = 1000
}
";
$index= "index [TABLE]_idx {
source = [TABLE]_src
path = /path/to/indexes/idx_[TABLE]
}
";
$tables= array('Cats', 'Dogs', 'Mouses');
foreach($tables as $table) {
echo str_replace('[TABLE]', $table, $source)."\n";
echo str_replace('[TABLE]', $table, $index)."\n";
}
?>
searchd {
listen = localhost:9306:mysql41
pid_file = /path/to/pid_file.pid
}
Now you can use this file just like a normal Manticore Search config:
[snikolaev@dev01 ~]$ searchd -c manticore.conf
