net.sf.katta.lib.lucene.ILuceneClient.search()
Searches with a given query in the supplied indexes for an almost unlimited ( {@link Integer#MAX_VALUE}) amount of results. If this method might has poor performance try to limit results with {@link #search(IQuery,String[],int)}. @param query The query to search with. @param indexNames A list of index names to search in. @return A object that capsulates all results. @throws KattaException
