: When it is initialized for the first time, how can I change it?

Frnacis, I'm not sure if you already figured this out, but the point of 
hte documentation that Chris refered you to is that it is a completley 
under the covers caching mechanism of Lucene on a per field basis -- there 
is no way to change it, or configure it.  It's sized according to the 
number of documents in the index and the number of terms in the Field.

If you execute an operation that requires Lucene to use that datastructure 
for a field, then Lucene will build it, and cache it for as long as the 
IndexReader is open.

: Solr offers no configuration for FieldCache, neither in solrconfig.xml nor 
anywhere else; rather, that cache gets populated automatically in the depths of 
Lucene when you do a sort (or also apparently, as Yonik says, when you use a 
field in a function query).

: >From the wiki: 'Lucene has a low level "FieldCache" which is used for 
sorting (and in some cases faceting). This cache is not managed by Solr it has 
no configuration options and cannot be autowarmed -- it is initialized the 
first time it is used for each Searcher.' (
