Re: Solr Case-sensitivity issue with search field name
Hi Shawn, Thanks for your reply. So you mean the field name can't be case insensitive when specifies in a query? I'm gonna stop doing research on this issue if this is confirmed...

Re: Solr Case-sensitivity issue with search field name
Hi wunder, Great advice! As a matter of fact, I choose to use upper case due to the document I indexed, but it is really pain in the ass when typing the field names all in upper case. I thought there probably would be a way to set field names case-insensitive. I was wrong, wasn't I?

Solr Case-sensitivity issue with search field name
Hi guys, I'm using Solr 4.0 and I recently notice an issue that bothers me a lot which is that if you define a field in your schema named 'HOST' then in the query you have to specify this field by 'HOST' while if you used 'host' it would throw an 'undefined field' error. I have done some googling while I only found a jira ticket which says this issue had been fixed: https://issues.apache.org/jira/browse/SOLR-873 https://issues.apache.org/jira/browse/SOLR-873 I know I can use copyField to accomplish this but I'm wonder if there a way to apply this change all the field on the fly not one by one ... Many many thanks in advance!

It appears that the issue you have linked is specific to the dataimport handler (importing from a database or another structured data source), not searching. I've always read that fields in a Solr schema are case sensitive. My own recommendation is that you pick a standard, either all uppercase or all lowercase, and that you stick with it. I prefer all lowercase myself. Thanks, Shawn
Re: Solr Case-sensitivity issue with search field name
Lower case is safer than upper case. For unicode, uppercasing is a lossy conversion. There are sets of different lower case characters that convert to the same upper case character. When you convert back to lower case, you don't know which one it was originally. Always use lower case for text. That avoids some really subtle bugs. wunder On Feb 28, 2013, at 3:47 PM, Shawn Heisey wrote: On 2/28/2013 3:40 PM, hyrax wrote: I'm using Solr 4.0 and I recently notice an issue that bothers me a lot which is that if you define a field in your schema named 'HOST' then in the query you have to specify this field by 'HOST' while if you used 'host' it would throw an 'undefined field' error.
