=== Limitations ===
* Accesses all pages in all namespaces - currently no configuration possible (but can be relatively easy changed in the code)
* Does not respect any read restrictions/access rights on MediaWiki content (certain access control is possible in WoogleRemote using an [[Integrated Search|Integrated search backend]])
* For minor limitions of specific releace also consult the [[Woogle4MediaWiki/Release Notes]]

=== Comparisons ===
Options for search in MediaWiki are described on [http://www.mediawiki.org/wiki/Extension:Woogle4MediaWiki#See_also Woogle's MediaWiki.org page] and at http://www.wiki4enterprise.org/index.php/Suche_in_Wikis (in German).

== Performance ==
* WoogleRemote
** [[Integrated Search]] is the core determinant for indexing and query performance - it can typically handle large amounts of data
** Communication and even network latency between the PHP/MediaWiki frontend and the Java/TeamWeaverIS backend is not an issue to our experience
* WoogleNative
** On state-of-the-art hardware, we were able to work with a 50,000 pages subset of Wikipedia, serving queries well below one second
** However, we did not yet test this scale with massive requests
** We recommend to restrict search-term autocomplete to title matches only for Wikis larger than 10,000 pages for performance reasons
