Can you please elaborate more on how exactly you want to "play around" with tokens and frequencies? Is your intention to produce scores for queries? Introspect stats on the index? Something else? ---

You may want to look at the [significant text aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/master/search-aggregations-bucket-significanttext-aggregation.html). ---

thank you for your reply ya i can use that aggregation feature but its a very costly operation on huge (1.5TB) indexed data so we choose to make plugin and iterate over all the terms with our custom logic so will you please suggest me some other solution using custom plugin for all term iterate ---

@jprante hello sir I am converting your plugin ( [https://github.com/jprante/elasticsearch-index-termlist](https://github.com/jprante/elasticsearch-index-termlist) ) from version elasticsearch v1.5 to v2.4.3 I successfully register plugin in newer elasticsearch but there is one problem with TransportTermlistAction for v2.4.3 ``` public class TransportTermlistAction extends TransportBroadcastAction { private final IndicesService indicesService; private final Class termlistRequestClass; private final Class shardTermlistRequestClass; private final String shardExecutor; private final IndexNameExpressionResolver indexNameExpressionResolver; @Inject public TransportTermlistAction(Settings settings, ThreadPool threadPool, ClusterService clusterService,TransportService transportService,IndicesService indicesService,ActionFilters actionFilters, IndexNameExpressionResolver indexNameExpressionResolver,Class termlistRequestClass,Class shardTermlistRequestClass,String shardExecutor) { super(settings, TermlistAction.NAME, threadPool, clusterService, transportService, actionFilters,indexNameExpressionResolver,termlistRequestClass,shardTermlistRequestClass,shardExecutor); this.indicesService = indicesService; this.termlistRequestClass = termlistRequestClass; this.shardTermlistRequestClass = shardTermlistRequestClass; this.shardExecutor = ""; this.indexNameExpressionResolver = indexNameExpressionResolver; } ``` and for v1.5 as you wrote ``` public class TransportTermlistAction extends TransportBroadcastAction { private final static ESLogger logger = ESLoggerFactory.getLogger(TransportTermlistAction.class.getName()); private final IndicesService indicesService; @Inject public TransportTermlistAction(Settings settings, ThreadPool threadPool, ClusterService clusterService, TransportService transportService, IndicesService indicesService, ActionFilters actionFilters, IndexNameExpressionResolver indexNameExpressionResolver) { super(settings, TermlistAction.NAME, threadPool, clusterService, transportService, actionFilters, indexNameExpressionResolver, TermlistRequest.class, ShardTermlistRequest.class, ThreadPool.Names.GENERIC); this.indicesService = indicesService; } ``` so here its giving error for 2.4.3 org.elasticsearch.common.inject.CreationException: Guice creation errors: 1. Could not find a suitable constructor in java.lang.Class. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private. at java.lang.Class.class(Unknown Source) while locating java.lang.Class\ for parameter 7 at org.xbib.elasticsearch.action.langdetect.TransportLangdetectAction.(Unknown Source) at _unknown_ 2.
