public void newSearcher(SolrIndexSearcher newSearcher,

Description copied from interface: SolrEventListener

The searchers passed here are only guaranteed to be valid for the duration of this method call, so care should be taken not to spawn threads or asynchronous tasks with references to these searchers.

• EventParams.FIRST_SEARCHER - First Searcher event
• EventParams.NEW_SEARCHER - New Searcher event

Sample:

    if (currentSearcher != null) {
      nlst.add(CommonParams.EVENT, CommonParams.NEW_SEARCHER);
    } else {
      nlst.add(CommonParams.EVENT, CommonParams.FIRST_SEARCHER);
    }

 

Specified by:

newSearcher in interface SolrEventListener

Overrides:

newSearcher in class AbstractSolrEventListener

Parameters:

newSearcher - The new SolrIndexSearcher to use

currentSearcher - The existing SolrIndexSearcher. null if this is a firstSearcher event.
