Bundle: org.eclipse.smila.lucene.pipelets.LuceneSearchPipelet
Description
This pipelet is used to execute a search using the LuceneSearchService.
Note on implementation: The LuceneSearchService is an own OSGi service named LuceneSearchService.
Configuration
Configuration
The LuceneSearchPipelet itself does not need any configuration, but the pipelet configuration part may be used to set default values for query parameters that are not set in the request records.
For information on configuring the LuceneSearchService see LuceneSearchService.
Example
The following example shows how the LuceneSearchPipelet is used for a Lucene search.
searchpipeline.bpel
... <extensionActivity> <proc:invokePipelet name="search"> <proc:pipelet class="org.eclipse.smila.lucene.pipelets.LuceneSearchPipelet" /> <proc:variables input="request" output="request" /> <proc:configuration> <rec:Val key="index">test_index</rec:Val> </proc:configuration> </proc:invokePipelet> </extensionActivity> ...
This sets a default index to search in, if the search request does not contain the "index" parameter itself. Default values for other query parameters may be set here in the same way.
