 All [[acl|access rights]] are respected, so users will only find pages for which they have at least read privileges.
 You can use the Advanced Search Tools to filter the results by namespace and date of the last modification.
+If the [[plugin:text|text plugin]] is installed, the rendered content of pages will be indexed in addition to raw wiki syntax. By default, search uses both fields. If you want to disable search in syntax, change the ''searchSyntax'' setting in the plugin's configuration.

 The name of the index is determined by the configuration.
+=== Re-creating the index ===
+Sometimes it is necessary to throw away the old index and replace it with a new one. This can be done via the same DokuWiki script with an additional parameter:
+<code>
+./bin/plugin.php elasticsearch createindex --clear
+</code>
 ==== Languages and fuzzy search ====

 If you have configured multiple languages using the [[plugin:translation|Translation plugin]], they will be mapped as well.
-At present there is no special filter that would let the user search in a particular language only. However, it is possible to filter the results by language namespaces.
+By default all available translation are searched. Users can change the language selection in Advanced Search Tools.
+You can also enable translation detection in the plugin configuration. The option is called ''detectTranslation''. When activated, the search will try to detect the current language context from the top namespace, and then set the language filter accordingly. For example, if the translation plugin is configured to handle the ''en es fr'' namespaces and the user starts the search when browsing the page ''es:capítulos:tres'', the language filter will be automatically set to ''es''.

+===== Other plugins =====
+The [[plugin:tagging|tagging plugin]] integrates well with Elasticsearch. You can search for tags explicitly using ''#sometag'' search terms. If any of the results are tagged, a tag filter will be added to Advanced Search Tools.
 ===== Development =====
+==== Plugin integration ====
+Elasticsearch emits several events that can be used by other plugins to put their own data into the search index. Take a look at the implementation [[plugin:tagging|tagging]] to see how those events can be used.
+  * ''PLUGIN_ELASTICSEARCH_CREATEMAPPING'': Triggered when creating the index. Plugins may add their own fields and mappings via event data.
+  * ''PLUGIN_ELASTICSEARCH_INDEXPAGE'': While indexing a page, plugins can provide their own data.
+  * ''PLUGIN_ELASTICSEARCH_FILTERS'': Adds search configurations provided by plugins.
+  * ''PLUGIN_ELASTICSEARCH_SEARCHFIELDS'': Lets plugins add their own fields to the list of search fields included in the Elastic query.
+  * ''PLUGIN_ELASTICSEARCH_QUERY'': Lets plugins append their data to the query string.
