public static boolean isIndexConsistent(String name,
int expectedCount,
Supplier<org.apache.lucene.search.IndexSearcher> supplier)
- Performs a simple consistency check on an index by opening it, comparing the document count to an
expected value supplied by the caller, and closing it. If the expected document count can not be
determined reliably and efficiently, then
-1
may be specified to skip that part of the
check. If an expected count is given, the actual count must be within 10%
of the expected
value or 10
documents, whichever value is larger.
- Parameters:
name
- a name to identify the indexexpectedCount
- the expected count of documents in the index, or -1
to skip this checksupplier
- provides a searcher for the index; should throw an exception if the index is unavailable
- Returns:
true
if the index is present and contains reasonably close to the expected number of documents;
false
if any exception is thrown or if the index document count is excessively different from the
expected count
