ClinetAbort exception doing *:* searches

[rajnemani .]

All,

We have recently switched a filed to index using NGramFilterFactory (minimum gramsize:4 and maximum gramsize 100) instead of EdgeGramFilterFactory and re-indexed and since then our *:* search is failing.  I do understand that *:* are not generally recommended and our users do not do that kind of search but I would like to know why this stopped working if possible.

Here is some stack trace.  It does look like it is a request timeout but I was wondering if it is possible to control this timeout from SolrNet if this becomes an issue from customer standpoint.

Any help is appreciated.

Thanks in advance

Raj

You can set the timeout for the connection as shown in this previous post:
