Mark Ebbert commented on SOLR-6051:
-----------------------------------
That's helpful, but we are on 4.6.X and the note is not in our schema.xml
(unless it was inadvertently deleted). In either case, the issue is clear.
Making it more clear in the official documentation is the only task remaining,
IMO.
Thanks!

> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.7.2
> Environment: CentOS 6+
> Reporter: Mark Ebbert
> Priority: Minor
> Labels: documentation, patch
>
> I've looked all over for specific field name requirements and can't find any
> official documentation. Is there official documentation on field names? If
> not, *please* provide some!
> We created several field names that begin with numbers, but SOLR doesn't seem
> to handle that well. Here are two "identical" URL queries that produce
> different output:
> {quote}
> http://<our_server>:8080/solr/query?q=chr:19%20AND%20pos:16666101&fl=chr,pos,ref,alt,1000G_freq,AFR_freq,ASN_freq
> {quote}
> and
> {quote}
> http://<our_server>:8080/solr/query?q=chr:19%20AND%20pos:16666101&fl=chr,pos,ref,alt,AFR_freq,ASN_freq,1000G_freq
> {quote}
> The only difference between the two queries is the location of '1000G_freq'
> (middle vs. end). The first query does not return the 1000G_freq value but
> the second does. Additionally, both return a value that does not exist
> ("1000":1000). Seems to be doing something funky with the 1000 in the field
> name. The "1000":1000 disappears if I remove '1000G_freq' from the query.
> Here are the outputs from both queries:
