Method Detail

createQueuedIndexManager

public static Index.Manager createQueuedIndexManager(@NotNull
                                                     String name,
                                                     @NotNull
                                                     Configuration config)

Creates an index where the index operations are placed on a queue and the actual work is done on a background thread. Any Index.Result may be waited on to make sure that subsequent searchers will see the result of that update, but you can timeout on that without losing the update.

Parameters:

name - used to name the background thread.

config - that holds the Directory and Analyzer used for indexing and searching.

Returns:

a Index.Manager that has an index configured for queued operations.

createSimpleIndexManager

public static Index.Manager createSimpleIndexManager(@NotNull
                                                     Configuration config)

Creates an index where the index operation work is done in the calling thread. Any Index.Result may be waited on but it will always be a non-blocking operation as it will be complete already. There is no way to timeout these operations.

The Index write policy is that flushes will only occur if a Searcher is requested, when the IndexWriter decides to according to its internal buffering policy, or when the index is closed.

Parameters:

config - that holds the Directory and Analyzer used for indexing and searching.

Returns:

a Index.Manager that has an index configured for direct operations.
