 org.apache.cocoon.transformation.LuceneIndexTransformer2
| LuceneIndexTransformer2 | | public class LuceneIndexTransformer2 extends AbstractTransformer implements Recyclable,Serviceable,Configurable(Code) | | Another lucene index transformer. allow
- index function (update indexing or add indexing if clear attribute is
true)
- lucene field boosting
- delete function
This tranformer used several avalon components, but you can use them
separatly :
- AnalyzerManager: you can setup a analyzer (configurable) in the
analyzer_manager tag in cocoon.xconf file
- IndexManager: you can setup a index in a the /WEB-INF/index.xml (default
location , but you can specify the location in the IndexManager component
configuration in cocoon.xconf file)
- Indexer (2 implementations: default (with update optimization) and
parallel implementation for multiple cpu)
Example of input source:
- to Index
<lucene:index xmlns:lucene="http://apache.org/cocoon/lucene/1.0"
indexid="myindex"
clear="true" (optinal attribute: clear index)
merge-factor="100">
(optinal attribute: see lucene doc)
<lucene:document uid="http://myhost/myfile1.data">
<lucene:field name="tile" > sqdqsdq </lucene:field>
<lucene:field name="description" > a text bla bal blalael
balbal</lucene:field>
<lucene:field name="date" >10/12/2002</lucene:field>
</lucene:document>
<lucene:document uid="http://myhost/myfile2.data" >
<lucene:field name="author" boost="2" >Mr Author </lucene:field>
(boost the field for the search (see Lucene documentation))
<lucene:field name="langage" >french</lucene:field>
</lucene:document>
< /lucene:index>
- To delete
<lucene:delete indexid="myindex" >
<lucene:document uid="http://myhost/myfile.data" >
<lucene:document uid="EODOED-EFE"
</lucene:delete>
Example of Output Source
<page xmlns:lucene="http://apache.org/cocoon/lucene/1.0">
< lucene:index >
<lucene:document uid="http://myhost/myfile1.data"/>
<lucene:document uid="http://myhost/myfile2.data"/>
</lucene:index>
<lucene:delete > <lucene:document
uid="http://myhost/myfile1.data"/>
<lucene:document
uid="EODOED-EFE"/>
</lucene:delete >
