give tiki_p_search to the groups that are allowed to search.

There are 2 search systems that can be configured by the administrator: (a) Basic Search (database search) and (b) Advanced search (tiki search) . In old versions, each one had a module, a tiki page that displayed the results and a set of settings.

• Old tiki versions:
  1. the Module search_box:
     It is called "database search". It uses the resources of the database to do the search and indexation. It can be used with or without fulltext capacity. You can see you are running this search if the search page is tiki-searchresults.php. If you enable full-text search, your results will be ordered according to their relevance to the search terms. In a similar way, a user knows it is a full text search because each result has a relevance indicator.
  2. the Module search_new:
     It is called the "database independent search" or "tiki search". The search resources are managed by tikiwiki. There is no fulltext capacity in this module. search_new was introduced in Tikiwiki 1.8. You can see you run this search if the search page is tiki-searchindex.php
  
  Both could be used as soon as you checked the feature search. You could even set the 2 search boxes.
• Current tiki versions:
  1. the Module search, which uses tiki-searchresults.php if the 'Basic Search' is enabled regardless of the choice for 'Advanced search'.

Uses MySQL Full-Text Search, through tiki-searchresults.php. If enabled, the search module and search feature at the main application menu will use it by default, even if 'Advanced Search' is also enabled below.

• search without case consideration
• don't index words less that 3 characters (no stoplist)
• relevance and ranking don't work . the relevance is based function of the object type on number od read, hits.... there is no ranking
• can search on a part of a word

Uses Unified Search Index, through tiki-searchindex.php. You must choose one unified search engine (default value, Lucene, is ok as a starting point).

1.1.2.1. Lucene (PHP Implementation)

There are a few options you can choose from, here.

1.1.2.2. Mysql Full Text Search

There are a few options you can choose from, here.

1.1.2.3. Elastic Search

You require an extenral server setup appropriately to use this search system.

• Cron Job to Rebuild Search Index

See http://dev.mysql.com/doc/refman/5.0/en/fulltext-fine-tuning.html for some setting at mysql level like the stop list words and the 4 character limit.

In v1.9 there is a new search box Module search_new and results page (tiki-searchindex.php) that together provide highlighting of search words. Additionally, by adding "&highlight=words", where words are the words you want to highlight, to the end of the URL (web address) for any wiki page, the words will be highlighted in the page.
