Features

ExtendedSearch replaces the default MediaWiki search engine. It is based on ElasticSearch engine, and provides many improvements over the standard MediaWiki search both in terms of quality of indexed content and user interface.

  • Search titles.
  • Search the full content.
  • Search uploaded or linked files (Office documents and PDFs).
  • Search image data.
  • Search-as-you-type and auto-complete.
  • Ignore upper and lower case (case-insensitive).
  • Search with the operators AND, OR, NOT.
  • Search with wildcards.
  • Search for phrases.
  • Fuzzy search.
  • Search for sentence fragments.

Some aspects of this extension can be configured on Special:BlueSpiceConfigManager, under section "ExtendedSearch". Here wiki administrators can configure:

  • external file paths
  • layout of the autocomplete box
  • language filter
  • exclude patterns

Boosting (server configuration)

For boosting by match percent, the following settings are available in the extension itself:
"ESMatchPercentBoostFactor": {
            "description": "How much to boost the result based on the percent of its title taken up by the search term. Set to 0 to disable",
            "public": false,
            "value": "0.5"
        },
        "ESMatchPercentTitleField": {
            "description": "Field on which to base the match percent boosting. If empty, default title field of the source will be used",
            "public": false,
            "value": ""
        },


System-wide boosting

BlueSpice influences the score, after the results have been retrieved, in the following ways:

  • Creation date / last edit: All things equal, more recently edited pages will rank higher. The amount of influence can be adjusted with '$bsgESRecentBoostFactor' (default 0.5). The value for this can be a number between 0 and 1. 0 means that recency of the page does not change the score and 1 means that very recent changes might get their score doubled.
  • Percent of the page title taken up by the search term: An additional score boost is assigned to results that match a larger part of the title. E.g., if the search term is “foo”, a page called “Foo Bar” will have a good match percentage (50%), since the search term takes 50% of the full page name. The page “Foo quick brown fox jumps” will have a lower percentage boost, because the search term takes up only a small percentage of the whole title. This is controlled by '$bsgESMatchPercentBoostFactor' (default 0.5). Same as for the previous setting, a value of 0 will effectively disable this kind of boosting, while 1 would double the score for exact matches (In our example, page “Foo Bar” would get 50% added to its original score).
  • Wikipages will always be boosted a bit more than other results types (repofile, socialentity, …)
  • Inside the “wikipage” type, pages in content namespaces and especially pages is NS_MAIN will be boosted additionally. Talk pages will receive no boost.


  • ESMatchPercentTitleField: Field on which the match analysis is performed. Defaults to nothing, so whatever the search lookup sets. It can be set to "prefixed_text" to calculate match percent on the title with namespace prefix, for example, or to something like "basename" to calculate the match percent only on the page name, without the namespace prefix.
