OJS Indexing/Searching Method

Hi! I’m currently using the DB structure in OJS Because I need to make a search engine for my institute which use OJS.

  1. What method OJS use for the indexing and searching?
  2. Which tables that are used to search? and also table for indexing?
    Is it just these (article_search_objects, article_search_keyword_list, article_search_object_keywords) table? Or is there anything else?
    Thank you very much.
    Merry Christmas and Happy New Year 2019 :slight_smile:
