robustness of OJS (searching)

Forum rules
This forum is meant for general questions about the usability of OJS from an everyday user's perspective: journal managers, authors, and editors are welcome to post questions here, as are librarians and other support staff. We welcome general questions about the role of OJS and how the workflow works, as well as specific function- or user-related questions.

What to do if you have general, workflow or usability questions about OJS:

1. Read the documentation. We've written documentation to cover from OJS basics to system administration and code development, and we encourage you to read it.

2. take a look at the tutorials. We will continue to add tutorials covering OJS basics as time goes on.

3. Post a question. Questions are always welcome here, but if it's a technical question you should probably post to the OJS Technical Support subforum; if you have a development question, try the OJS Development subforum.

robustness of OJS (searching)

Postby romca » Wed Oct 19, 2005 11:50 pm

Hi all,

I am trying to investigate if OJS is a good choice for e-journal Ikaros. The journal exists for nine years and there are virtually thousands of articles (do not know the exact number, but there could be about 2.000 articles, and that is still not everything - there are comments, special issues, short news and other, see http://www.ikaros.cz/archiv.asp ).

As I know that searching with PHP makes the index extremely big and sometimes performace may be an issue, I would like to ask you your opinion (I also have not seen any OJS e-journal yet that would have as many vols/issues as Ikaros)

There is a short discussion on searching with a link to some more information, unfortunately, bugzila is probably not working
viewtopic.php?t=473

The journal should be placed on some shared webhosting, I can not believe that processor's time will be exclusively dedicated to us, so what do you think? Is OJS searching able to work with thousands of articles without performance penalty?


thanks for any comments/help

Hello Roman,

The discussion at http://pkp.sfu.ca/support/forum/viewtopic.php?t=473 relates to a missing index; this can be corrected by executing the following in MySQL:
Code: Select all
CREATE UNIQUE INDEX article_search_keyword_text ON article_search_keyword_list (keyword_text);


With this index in place, we currently know of no performance issues with OJS 2.x's searching and indexing. A number of OJS 2.x journals are available for browsing at http://journals.sfu.ca if you'd like to assess for yourself.

OJS 2.x has been deployed in many shared hosting environments without issue.

Regards,

Hello Alec,

thank you - now I see that the code is for building an index in MySQL (for faster queries).

I have also gone through many OJS installations, but never seen any with that many (say at least 20) issues. Almost all OJS installations were quite fresh (at least what I have seen).

I would be grateful if you could post some link, or maybe, you developers, have already tried a configuration with many many articles, did you?

The task of exporting/importing data is stil ahead, so I can not try it myself now, I am sorry. It would definitely be easier to use OJS search ability, but if it can not deal with thousands of articles, I will have to employ an external search engine - this is also one point of evaluation criteria.

thank you
