The Content Indexes power Confluence's search functionality and they are also used for a number of related functions such as building email threads in the mail archive, the Space Activity feature and lists of recently-updated content. The Gliffy Plugin also uses them for some of its functionality.

For reasons of efficiency, content is not immediately added to the index. New and modified Confluence content is first placed in a queue and the queue is processed once every minute (by default).

Viewing the Content Index Summary

To see information about your Confluence instance's content indexing,

    • Open the 'Browse' menu and select 'Confluence Admin'. The 'Administration Console' view will open.
  2. Click 'Content Indexing' under the heading 'Administration' in the left-hand panel.

Rebuilding the Content Indexes

The content indexes are maintained automatically, but you may need to rebuild one or both of them manually under circumstances such as these:

  • Your searching and mail threading are malfunctioning. (Rebuild the Search Index.)
  • Your 'Did You Mean' feature is malfunctioning. (Rebuild the Did You Mean Index.)
  • After an upgrade. If a content re-index is required after an upgrade, it will be noted in an upgrade subsection of the relevant release notes.

In new Confluence installations, the 'Did You Mean' feature is not initially activated. To activate it, you first need to build its index by clicking its 'Build' button on this page.

To rebuild either of the content indexes,

  1. Go to the Confluence 'Administration Console'. To do this:

    • Open the 'Browse' menu and select 'Confluence Admin'. The 'Administration Console' view will open.
  2. Click 'Content Indexing' under the heading 'Administration' in the left-hand panel.
  3. Click the 'Rebuild' button in either the 'Search Index' or 'Did You Mean Index' sections on this page, depending on the particular index you want to rebuild.
  • If one of these indexes has not yet been built, its button will indicate 'Build' (instead of 'Rebuild').
  • As shown in the image below, only one index can be (re)built at a time.

Slow Reindexing

インデックス再作成は完了までに長い時間がかかるのでしょうか? 時間の長さは次の要因に依存します。

  • Confluence インスタンスにおけるページ数。
  • 添付ファイルの数、タイプ、およびサイズ。
  • Confluence に割り振られたメモリの量。

It may help to increase the heap memory allocation of Confluence by following the instructions in the JIRA documentation.

Confluence の古いバージョンを実行していて、インデックスの再構築が進行していないことを確認した場合、Confluence をシャットダウンし、Java システムプロパティを bucket.indexing.threads.fixed=1 に設定して再起動する必要がある場合があります。これにより、インデックス再作成がシングルスレッドで、安定して実行されるようになります (速度は低下します)。

Viewing the Index Browser

You can access the Lucene index browser used with Confluence, to see if the required documents have been added to the index.

To view the index browser,

  1. Open a browser window.
  2. Confluence にログインします。
  3. Type the following into the browser address bar: <Confluence location>/admin/indexbrowser.jsp.
    For example: 
    http://localhost:8080/admin/indexbrowser.jsp
  4. You will be asked "Which index would you like to browse?"
  5. Type in the path of your index directory. By default, this is located at <Confluence Home directory/index>.
    For example, c:\confluence\data\index.
  6. You should see a list of indexed file names.

More Hints and Tips

  • If you are still experiencing problems after performing the above rebuild, the next step might be to remove the index and rebuild it from scratch.
    (warning) The Space Activity feature uses the index to store data. If you remove the index file, the existing activity data will disappear.
