Simone, You can set up a "master" dictionary but with a few caveats. What you'll need to do is <copyfield> all of the fields you want to include in your "master" dictionary into one field and base your IndexBasedSpellChecker dictionary on that. In addition, I would recommend you use the "collate" feature and set "spellcheck.maxCollationTries" to something greater than zero (5-10 is usually good). Otherwise, you probably will get a lot of ridiculous suggestions from it trying to correct words from one field with values from another. See http://wiki.apache.org/solr/SpellCheckComponent#spellcheck.collate for more information.
There is still a big problem with approach, however. Unless you set "onlyMorePopular=true", Solr will never suggest a correction for a word that exists in the dictionary. By creating a huge "master" dictionary, you will be increasing the chances that Solr will assume your users' misspelled words are in fact correct. One way to work around this is instead of blindly using "copyField", to hand-pick a subset of your terms for the master field on which you base your dictionary. Another workaround is to use "onlyMorePopular", although this has its own problems. See the discussion for SOLR-2585 (https://issues.apache.org/jira/browse/SOLR-2585), which aims to solve these problems.

In the meanwhile I configured two spellcheckers and let users switch from a checkeer to another via params on GET request, but looks like people are not particularly happy about it... The main problem is that fields I need to speel contain different informations, I mean the intersection between the two sets could be empty. Many thanks in advance, all the best!
