If you want to start learning Manticore Search plain indexes or see how some its feature works the following simplest Manticoresearch configuration might be useful:
source min { type = mysql sql_host = localhost sql_user = root sql_pass = sql_db = test sql_query = select 1, 'cat' union select 2, 'dog' } index idx_min { path = idx source = min } searchd { listen = 9306:mysql41 log = searchd.log pid_file = manticoresearch.pid binlog_path = }
It contains almost nothing, but only the things Manticoresearch cannot work without. Those are:
- Section “source” to fetch data from mysql. In this case we don’t even fetch real data from mysql, but just use mysql interface having the data defined right in the config (“select 1, ‘cat’ union select 2, ‘dog'”). It will create 2 documents in Manticoresearch: one containing word “cat”, another one with word “dog”, the ids are 1 and 2 respectively.
- Section “index” to create index based on the above source, it contains only reference to the source (“source = min”) and path to the index (“path = idx”). Once you build this index files idx.* will be created in the dir you start ‘indexer’ from.
- Section “searchd” to tell Manticoresearch what ports it should be listening (“listen = 9306:mysql41” which means that SphinxQL should be used to talk to Manticoresearch on this port), what log it should use (“log = searchd.log”) and where it should save its process id (“pid_file = manticoresearch.pid”).
Here’s an example of using this config:

When searchd is running if you want to rebuild the index you can do it without stopping the searchd if you run indexer --rotate:
[snikolaev@dev01 ~]$ indexer -c min.conf --all --rotate Manticore 2.6.1 9a706b4@180119 dev Copyright (c) 2001-2016, Andrew Aksyonoff Copyright (c) 2008-2016, Sphinx Technologies Inc (http://sphinxsearch.com) Copyright (c) 2017-2018, Manticore Software LTD (http://manticoresearch.com)</pre> using config file 'min.conf'... indexing index 'idx_min'...

As you can see in the last line the indexer sent signal to the searchd to make it rotate the index.
The ‘indexer’ command used seems to have gone missing. quite easy to deduce if know how (eg `indexer -c min.conf idx_min`), but should be there for reference. also think it would be really nice to show a second indexer call (with –rotate) after searchd is running!
Thanks Barry. I’ll update the article soon.
