Hi
After your email I had a look around and came up with the below
solution (I'm not sure if this is the right approach or there is a
performance implication to doing this)
public Summary[] search(SearchRequest searchRequest) {
List<Summary> summaryList = new ArrayList<Summary>();
StopWatch stopWatch = new StopWatch("searchStopWatch");
stopWatch.start();
MultiSearcher multiSearcher = null;
List<IndexSearcher> newIndexSearchers = new
ArrayList<IndexSearcher>();
try {
for (IndexSearcher indexSearcher: searchers) {
IndexReader indexReader =
indexSearcher.getIndexReader().reopen();
IndexSearcher indexSearch = new
IndexSearcher(indexReader);
newIndexSearchers.add(indexSearch);
}
multiSearcher = new MultiSearcher(newIndexSearchers.toArray(new
IndexSearcher[] {}));
QueryParser queryParser = new
MultiFieldQueryParser(FieldNameEnum.fieldNameDescriptions(), analyzer);
Query query =
queryParser.parse(searchRequest.getSearchTerm());
//TODO: Sort and Filters
TopDocs topDocs = multiSearcher.search(query, 100);
ScoreDoc[] scoreDocs = topDocs.scoreDocs;
LOGGER.debug("total number of hits for [" + query.toString() + " ]
= " +topDocs.totalHits);
for (ScoreDoc scoreDoc : scoreDocs) {
final Document doc =
multiSearcher.doc(scoreDoc.doc);
float score = scoreDoc.score;
final BaseDocument baseDocument = new
BaseDocument(doc, score);
Summary documentSummary = new
DocumentSummaryImpl(baseDocument);
summaryList.add(documentSummary);
}
} catch (Exception e) {
throw new IllegalStateException(e);
}
stopWatch.stop();
LOGGER.debug("total time taken for seach: " +
stopWatch.getTotalTimeMillis() + " ms");
return summaryList.toArray(new Summary[] {});
}
The searchers are configured in spring using which looks like this:
<bean id="rtfIndexSearcher"
class="org.apache.lucene.search.IndexSearcher" scope="prototype" lazy-
init="true" >
<constructor-arg type="org.apache.lucene.store.Directory"
ref="rtfDirectory" />
</bean>
I set the dependencies on the DocumentSearcher class.
Cheers

}
Do I need to do this explicitly?

After you make the commit to the index, are you reloading the index
in the
searchers?

Hi
I have recently worked on developing an application which allows
you to
upload a file (which is indexed so you can search later). I have
numerous
tests to show that you can index and search documents (in some
instances
within the same test), however when I perform the operation in the
site:
1) Upload File and Index
2) Search
I don't get any hits. When I restart the application then if I make
another search I can find the results. It seems as though indexes
aren't
being committed when I do the initial upload. This is strange. I
explicitly call commit in my code when I upload the file. Has
anyone
experienced this before?
Any help would be appreciated.
Kind Regards
Amin
