Hi All, I am executing a cluster query to fetch the documents and cluster it using Carrot2. If I am doing the query with the words " **mobiles, samsung, test**" it works fine but if I do the query with word " **mobile**" it is giving the following exception. **error: ReduceSearchPhaseException[Failed to execute phase [fetch], [reduce] ]; nested: c[bytes can be at most 32766 in length; got 131074]; status: 503** Any solution to solve such type of exception or how I can find the root cause for the same? ---

Prahy, Although I don't know the solution, It does look like using a RegEx in your query is causing an overflow of a byte length limit. Accordingly, I suspect if you can find the setting for that, it should solve your problem. Tony -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Tony, I am not using any Regex in my query explicitly. Is there any place in config file or somewhere else where I can confirm for the same if its taking internally? ---

Ok Dawid, waiting for your reply... Some info which might help wrt ES and all I am using: ES version: 1.0.1 Lingo3g Version: 1.9.0 Clustering Plugin version: 1.3.0 ---

This is a bug in Lingo3G. It will only manifest itself if you have single tokens ("words") that exceed over 30k in UTF8... So in reality it shouldn't be the case unless you're trying to cluster languages without whitespace delimiters (and with incorrect language preprocessing option for Lingo3G). Could you provide a repeatable test case to my e-mail address if the above is not the case? We will try to fix the bug in the next release but I still think you should cluster on fields that don't contain such awkward tokens.

I have sent the particular scenario in which I am getting the error. Also I am using common words token only for search not any awkward tokens. So just let me know if the issue gets fixed or any temporary solution is there to solve the same. ---
**Author:** ![Prashant\_Pal](https://avatars.discourse-cdn.com/v4/letter/p/b77776/32.png) [@Prashant\_Pal](https://discuss.elastic.co/u/Prashant_Pal)\ **Post date:** [March 4, 2014, 7:07am UTC](https://discuss.elastic.co/t/error-reducesearchphaseexception/16030/10 "2014-03-04T07:07:56Z")
One more observation in above scenario. 1. The records returned by the "mobile" is 287 so if I set the "size" (in query) as \< 287 it is working fine but in case of \>=287 it is throwing the exception. 2. The records returned by the "samsung" is 191 so if I set the "size" as \< 191 it is working fine also in case of \>=191 it is working fine. So just to conclude the keywords which are throwing exception works fine if I am giving the size \<= total records. But I hope it(size) shouldn't be dependent on the number of records returned. ---

Hi, While doing the clustering with wild card search its giving the exception but without wild card its working fine. for ex. executing the below query works fine: { "search\_request": { "fields": [ "Content", "SessionAtt" ], "query": { "query\_string": { "query": "com", "fields": [ "Content", "SessionAtt" ] } }, "size": 500, "from": 0, "highlight": { "fields": { "Content": {}, "SessionAtt": {} } } }, "query\_hint": "company", "field\_mapping": { "content": [ "fields.Content", "fields.SessionAtt" ] }, "algorithm": "lingo3g" } But instead if i modify the query string query as "query": "_com_", this throws the same exception as mentioned in previous posts. So is there any workaround for the same? ---
