public void addDataToLuceneDocument(org.apache.lucene.document.Document luceneDoc,
                                    com.xpn.xwiki.doc.XWikiDocument doc,

Short introduction to Lucene field types

Which type of Lucene field is used determines what Lucene does with data and how we can use it for searching and showing search results:

• Keyword fields don't get tokenized, but are searchable and stored in the index. This is perfect for fields you want to search in programmatically (like ids and such), and date fields. Since all user-entered queries are tokenized, letting the user search these fields makes almost no sense, except of queries for date fields, where tokenization is useless.
• the stored text fields are used for short texts which should be searchable by the user, and stored in the index for reconstruction. Perfect for document names, titles, abstracts.
• the unstored field takes the biggest part of the content - the full text. It is tokenized and indexed, but not stored in the index. This makes sense, since when the user wants to see the full content, he clicks the link to vie the full version of a document, which is then delivered by xwiki.

Parameters:

luceneDoc - if not null, this controls which translated version of the content will be indexed. If null, the content in the default language will be used.

buildQuery

public org.apache.lucene.search.Query buildQuery()

Builds a Lucene query matching only the document this instance represents. This is used for removing old versions of a document from the index before adding a new one.

Returns:

a query matching the field DOCUMENT_ID to the value of #getId()

getId

public java.lang.String getId()

Returns:

string unique to this document across all languages and virtual wikis

getFullText
