Potential BC break for subattribute fields in eZ Find 2.3: input requested

Wednesday 16 June 2010 3:16:27 am

While field names in Solr are in principle fully unicode, there are some areas where hyphens (or dash '-') pose problems. This is used in particular with subattribute field names.

I want to change this convention and replace the hyphen with an underscore ('_').

Apart from a re-index need, this will break cases where you use hardcoded fields names in templates for example when using subattribute filtering.

I would like to have an idea how many of you use hard coded subattribute fields and your comments on this change

Regards

The point is to avoid special characters which are actually also part of the lucene query syntax:

+ - && || ! ( ) { } [ ] ^ " ~ * ? : \

An alternatve is to use a pattern with multiple characters to aid human readability

For example

 _SUB_

as a separator

More thoughts?

ok, last chance to influence me:

what about '___' which are three consecutive underscores?

examples:

submeta_related_article___class_name_s

subattr_related_article___body_t

Is that clear enough to see the attribute and subattribute identifiers?
