field alias limit?

[jagresz]

Hi,

Are there any limitations in amount of alias fields or is it a bug in 4.3.2 that fields are randomly aliased?

I want to collect return codes extracted from several sources with field aliases, and if I search:

search * | top ret-code1 (ret-code1 is the field extraction regex for source1, it gives 1000s hits)

search * | top common-ret-code (common-ret-code is the fieldalias name, it gives just couple of hits)

I digged in archive but not found relevant answer.

Thanks in advance:

JI

Note: if I create a new fieldalias it works perfect! (common-ret-code contains several field aliases, this new contains only one) Still, I want to use common-ret-code, create a new one is not an option for me!
Thanks!
