> NRTSuggesterBuilder扩展input时溢出

> Key: LUCENE-10607
> URL: https://issues.apache.org/jira/browse/LUCENE-10607
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/FSTs
> Affects Versions: 9.2
> Reporter: chaseny
> Priority: Major
> Fix For: 9.3
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h

> suggest模块在创建索引时，调用NRTSuggestBuilder的finishTerm来写入suggest索引。
> 会调用maxNumArcsForDedupByte函数来扩展analyzed,向后扩展3 5 7 .... 255。
> 当entries长度过长（9000000）时，调用maxNumArcsForDedupByte扩展时
>
> private static int maxNumArcsForDedupByte(int currentNumDedupBytes) {
> int maxArcs = 1 + (2 * currentNumDedupBytes);
> if (currentNumDedupBytes > 5)
> { maxArcs *= currentNumDedupBytes;
> //当currentNumDedupBytes大于等于32768时，int相乘会大于int最大值 }
> return Math.min(maxArcs, 255);
> }
>
> 另外在扩展时，是否可以选择固定4字节来有序扩展。代替 3 5 7 ... 255的扩展方式
