solr break up word
Hi, I've solr running on a CentOS server working OK, but sometimes my application needs to index some parts of a word. For example, if I search 'dislike' word fine but if I search 'disl' it returns zero. Also, if I search 'disl*' returns some values (the same if I search for 'dislike') but if I search 'dislike*' it returns zero too. So, I've two questions: 1. How exactly the asterisk works as a wildcard? 2. What can I do to index properly parts of a word? I added this lines to my schema.xml: But I can't get it to work. Is OK what I did or I'm wrong? Thanks. -- Boris Quiroz boris.qui...@menco.it

Hi Erick, I'll try without the type="index" on analyzer tag and then I'll re-index some files. Thanks for you answer.

Re: solr break up word
Hi, I solved the issue. I added to my schema.xml the following lines: ... ... Then, I re-index and everything is working great :-) Thanks for your help.

weird issue with solr and CentOS 5.7
Hi all,
I'm facing a real weird issue here with solr (lucene 3.3) and CentOS
5.7. I've two servers, one running CentOS 5.5 and the other running
CentOS 5.7. Both servers has the same solr, java and tomcat versions,
the only difference between them is OS version.
I added a custom field to schema.xml: . When
that type is boolean, on CentOS 5.5 works OK indexing Chinese
characters, but on CentOS 5.7 I got this exception:
Nov 22, 2011 11:27:11 PM org.apache.solr.core.SolrCore execute
INFO: [] webapp=/solr path=/select/
params={indent=on&start=0&q=我们从右上角讲起&rows=10&version=2.2} hits=1

That only happens on CentOS 5.7. I also tested on Ubuntu Server, and
also works OK.
solrconfig.xml and everything else is the same on both servers. Any
idea what could be happening? Should it be a CentOS bug?
Regards.
