What are the issues with index naming?

[the_wolverine]

What other issues should we be aware of?

Are there issues with using special characters like "." or numerals in web2.0:

index=web2.0

yes, likely, use "underscore" to check.

index=web2_0

`******************************************************************************
PER INDEX OPTIONS
These options may be set under an [] entry.

Index names must consist of only numbers, letters, periods, underscores, and hyphens.
