19 The Lucene search has several benefits over web search:
20 * It indexes attachments (such as PDFs or MS Word documents) searchable. It does not replace the search page itself but rather makes more content available for searching.
21 * It provides a scoring for the search results.
22 * It offers pagination when there are lots of results.
23 * It scales well when there are lots of documents in the wiki.
24 * It supports multi wikis.
25 * It supports a strong query syntax.
26
27 === New search configuration UI ===

31 The Search Application now has a dedicated section in the wiki administration section from which you can:
32 * Choose the default engine (Lucene or Web).
33 * See the status for the Lucene Search: the number of indexed elements and the number of elements waiting in the queue.
34 * Control the Lucene index by indexing the whole farm, indexing the wiki or customizing the index to your specific preferences.

78 = Backward Compatibility and Migration Notes =
79
80 == General Notes ==
81
82 {{warning}}
83 If you're running in a multiwiki setup you'll also need to define the property //xwiki.store.migration.databases=all// to your //xwiki.cfg// file or explicitly name all databases to be migrated as in //xwiki.store.migration.databases=db1,db2,...//.
84 {{/warning}}
85
86 You may also want to [[import the default wiki XAR>>Main.Download]] in order to benefit from the improvements listed above.
87
88 {{warning}}
89 Always make sure you compare your //xwiki.cfg// file with the newest version since some configuration parameters were added. Note you should add //xwiki.store.migration=1// so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
90 {{/warning}}
91
92 == Migration Notes ==
93
94 * the main entry point for search UI is now the Main.Search page that will use the configured search engine (Lucene by default), if you explicitly want to refer to Lucene or Database search you can ##Main.LuceneSearch## and ##Main.DatabaseSearch## pages. Note that nothing is broken here (##Main.WebSearch## page is still there and include ##Main.DatabaseSearch## page), it's just the new clean way of targeting the search page.
