IndexJob.setActionVerify Method

Verify that an index is not damaged.

public void setActionVerify(boolean actionVerify);

The setActionXXX flags specify the actions you want the engine to perform. If more than one action is specified, the engine will perform the actions in the following order: create, removeDeleted, removeListed, add, compress, merge, verify. 

A brief summary of the meaning of each actionXXX flag is given below. For more information, see "Building and Maintaining Indexes" in the Overviews section. 

Add: Add documents to an existing index. 

Compress: Remove obsolete information from the index. 

Create: Create a new index. If an index already exists in the specified directory, the index will be destroyed and replaced with a new, empty index. 

RemoveDeleted: Check that each file in the index still exists on disk and remove from the index any files that no longer exist. 

RemoveListed: Remove the files listed in ToRemoveList from the index. 

Merge: Merge one or more indexes into the target index. Use setIndexPath to specify the location of the target index, and setIndexesToMerge to specify the location of the indexes to merge. Merging indexes combines two or more indexes into a single index, which contains any document that was in any of the merged indexes. If the same document appears in more than one of the merged indexes, only the most recent document will appear in the merged index. 

Verify: To verify an index, dtSearch scans all structures in the index and performs many detailed checks to validate all data in the index for consistency.
