It is not possible out of the box. However, there are a couple of ways to do this. 1. You can create a copy field for 'NAME' (say 'NAME_SPELL') which has a value only if "TYPE"="UNIVERSITY" for the document. 2. You can create your own implementation of the IndexBasedSpellChecker and HighFrequencyDictionary which applies a filter query on "TYPE" and then uses the terms to create the dictionary. Option #1 would be probably be the easiest if you care only about "TYPE"="UNIVERSITY". > 2) my current data index size is about 11G, and the spelling dictionary > index size is about 6 G.
