What are the commonly used index options and what do they do?
Building with this option enabled will check for both new files and modified files. Modifying fields also counts as modifying files and will cause a rebuild. This will not remove deleted files from the index.
Building with this option enabled will check for files that are removed from the index and mark these documents as deleted. This means that they can no longer be found in the index. This does not actually remove the contents from the index, so the index will not be smaller.
Building with this option enabled will compress all the internal databases of the index and actually remove all the entries marked as deleted. It will also completely recreate the index files. This will make the index smaller and faster. This option should not be used on a daily basis, but e.g. scheduled during the weekend as it is a costly operation and it is best performed when the index is not in use.
Building with this option enabled will only build the files that are present in the quickbuild table of the index and is only available when no other build options are enabled and when the index has quickbuild enabled as index setting. Any change to a document performed from ZyLAB applications will cause those files to be marked for quickbuild and will allow for a very fast build to only add the recent changes to the index.
Add documents from Index Catalog
Building with this option will only have an effect when the index was erased and the Catalog option was checked during erase. This means that the index was not completely erased; all the file references were kept. Indexing will not scan the directories for the files to index, but will use the index catalog and re-index all files that were present in the index prior to erasing it. This is commonly only used for EDRM produced indexes as the files for these indexes are not in the actual index data, but only in the index catalog
Update: Comment Only
Building with this option enabled will only update the fields cache of the index to take new maximum shown field lengths into account. This is an advanced option that can be configured per field and is on 500 characters per field by default.
Building with this option enabled is only possible when Data Extraction is enabled for an index. This is a separate indexing phase that will extract the data specified. After data extraction a new build using only Add will automatically happen to add the newly extracted data to the index.
Generate Report Database
Building with this option enabled will generate a reports database after indexing. This can be run on an already build index, without any of the other build options enabled to just generate the indexing report. The report will contain information on the amount of files that were indexed and also the amount of files that had indexing issues and group them on the various known indexing issues.
