Method Detail

getInstance

public static LuceneMemberSearchEngine getInstance()
                                            throws java.lang.Exception

Retrieve the LuceneMemberSearchEngine singleton.

After engine has been started during Channel startup, use Channel.getMemberSearchEngine() to retrieve singleton getter without having to catch exception.

Returns:

the LuceneMemberSearchEngine singleton.

Throws:

java.lang.Exception - if was not initialized and the initialization failed.

Since:

jcms-6.1.0

getAnalyzer

protected org.apache.lucene.analysis.Analyzer getAnalyzer(java.lang.String lang,
                                              boolean indexing)

Description copied from class: LuceneDataSearchEngine

Retrieve the lucene Analyzer to use during search and indexing.

Overrides:

getAnalyzer in class LuceneDataSearchEngine

Parameters:

lang - the language in which to perform search/indexing may be null

indexing - true if used during indexing false otherwise

Returns:

an instance of Analyzer to use

getDirectory

public org.apache.lucene.store.FSDirectory getDirectory()

Returns the lucene directory used by this LuceneMemberSearchEngine.
Warning!!! you should not modify the index, use this method only to access the directory in readonly !.

Returns:

the instance of the FSDirectory used internally.

Since:

jcms-6.1.0

getIndexingDate

public java.util.Date getIndexingDate(Member mbr)

Retrieve the Date at which the specified Member was indexed.

Parameters:

mbr - the Member for which to retrieve the indexing date.

Returns:

the indexing date of the Member or null if was not indexed.

Since:

jcms-6.1.0

searchPage

public PageResult<Member> searchPage(AllMemberQueryHandler amqh)

Search all members (Member and DBMember) using the specified criteria.

No more than getMaximumResults() Members will be returned, if this limit is reached, attribute MAXIMUM_RESULTS_NUMBER_REACHED is added to the AllMemberQueryHandler with the total count of Member retrieved.

Parameters:

amqh - the AllMemberQueryHandler instance specifying search criteria.

Returns:

a new PageResult of Member, null may be returned in case of internal error

Since:

jcms-6.1.0

search

public java.util.LinkedHashMap<java.lang.String,java.lang.Float> search(AllMemberQueryHandler amqh)

Search all members (Member and DBMember) using the specified criteria (paging excepted).

No more than getMaximumResults() Members will be returned, if this limit is reached, attribute MAXIMUM_RESULTS_NUMBER_REACHED is added to the AllMemberQueryHandler with the total count of Member retrieved.

Parameters:

amqh - the AllMemberQueryHandler instance specifying search criteria.

Returns:

a new map of Member id to relevance, may return null on internal error

Since:

jcms-6.1.0

getMaximumResults

public static int getMaximumResults()

Retrieve the maximum number of results allowed to be return for a search.

Can be configured using property query.lucene.mbr.max-results

Returns:

a number of result above which search is not performed
