[jira] [Updated] (LUCENE-4104) Clearly document the limit for
maximum number of documents in a single index
[ https://issues.apache.org/jira/browse/LUCENE-4104?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jack Krupansky updated LUCENE-4104:
-----------------------------------
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.
