fr.gouv.culture.sdx.search.lucene.query.Terms
A list of terms for a document base. The terms are single values of fields. One can build one list of all the terms, a list of terms which respect one regular expression (with an aim of managing truncation), one list of terms for a field, as well as a list of terms for a field according to a search acceptRequest.

IMPORTANT : only one search location is actually used. TODO : fix this...
Criterias are field=value pairs. This method lets a developer creates hierarchical lists.
There should be one value less than fields; the last field will then be the field to return values from.
For instance, if the first field is 'region', the second is 'department' and the third is 'city', and the first value is 'Aquitaine' and the second value is 'Gironde', you will get a list of cities that appear in documents that also have region=Aquitaine and department=Gironde.

- The list of values (there should be one less value than fields).
