Subject [jira] [Commented] (SOLR-3207) Add field name validation
Date Thu, 15 Mar 2012 16:41:38 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3207?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13230287#comment-13230287
] 

Yonik Seeley commented on SOLR-3207:
------------------------------------

bq. same used for java identifiers (Character#isJavaIdentifierPart), plus the use of trailing
'.' and '-'

I think we should prob define it as I documented in the schema:

   <!-- field names should consist of alphanumeric or underscore characters only and
      not start with a digit.  This is not currently strictly enforced,
      but other field names will not have first class support from all components
      and back compatibility is not guaranteed.
   -->

> Given the SOLR-2444 updated fl syntax and the SOLR-2719 regression, it would be useful
to add some kind of validation regarding the field names you can use on Solr.
> The objective would be adding consistency, allowing only field names that you can then
use within fl, sorting etc.
> The rules, taken from the actual StrParser behaviour, seem to be the following: 
> - same used for java identifiers (Character#isJavaIdentifierPart), plus the use of trailing
'.' and '-'
> - for the first character the rule is Character#isJavaIdentifierStart minus '$' (The
dash can't be used as first character (SOLR-3191) for example)
