I agree, IMO we should try to keep TermIndexInterval and Divisor together both 
should be settable in the <indexDefaults> section 
Additionally overriding those in a IndexReaderFactory section seems to be 
reasonable to me. question, is it possible to have more than one IR factory and 
use them in different places, I can't think of one from the top of my head 
since I never saw that param before?

If we enable setting IndexDivisor values in indexReaderFactory sections do we 
need to have the set prefix? <int name=:TermIndexDivisor">1</int> seems to be 
nicer or is this a set via reflection to a bean setter?

I don't think we should change any of this under this issue, I agree with yonik 
its a bug.
I think it should simply be renamed back to divisor to match how it worked in 
Solr 1.4

Regarding the patch, we should also change it in Example conf in 
solr/example/solr/conf/solrconfig.xml .

Yes, i agree we should change the commented-out example there.

> To change the terms index divisor: you currently do this:
> {noformat}
>   <indexReaderFactory name="IndexReaderFactory" 
> class="org.apache.solr.core.StandardIndexReaderFactory">
>     <int name="setTermIndexInterval">12</int>
>   </indexReaderFactory >
> {noformat}
> But to change the terms index interval, you do this:
> {noformat}
> <indexDefaults>
> ...
> <termIndexInterval>256</termIndexInterval>
> ...
> </indexDefaults>
> {noformat}
> I feel the IR parameter should be *setTermIndexDivisor* or similar instead:
> the name is very misleading and someone could easily put a terrible value 
> in the wrong place by confusing the two.
