      Description

      Although the "int" in a number of APIs strongly suggests the approximate limit to the number of documents than can exist in a single Lucene index, it would be useful to have the specific number more clearly documented.

      My reading suggests that the limit is 2^31-2 so that the count of documents, 0 to 2^31-2, will fit in an int as Integer.MAX_VALUE or 2^31-1 or 2,147,483,647.

      Symbolic definitions of the maximum document number and maximum number of documents, as well as the first document number should also be provided.

      A subsequent issue will be to detect and throw an exception when that limit is exceeded.
