The indexer progress bar shows the progress status of the indexing
jobs in the progress views.
The indexing jobs can be temporarily paused by pressing the stop
button on the progress bar. This will cause the indexer to wait until
the next time the user runs a search job or makes a change to an
indexed element (by such actions as modifying an existing source file,
deleting a file, creating a new file, moving file and so on). The
indexer at this point will resume with the previously postponed
indexing job before moving on to the new one.
If you wish to cease indexing all together, you can cancel an
indexing job and disable the indexer through the properties.
